First, please be aware that not everyone enjoys noise like the following,
due to your posting in both HTML and plain text. HTML enabled clients
are a security vulnerability that not everyone chooses to risk, and
often, the regulars most likely to have good answers are also the ones
you're offending by posting such noise. If it's worth reading, it's
worth reading in plain text only, so please, don't post the HTML. (Left-

As to the question...
FWIW, I actually use a couple instances of yawp here, set to different
locations, but don't use any of the other plasmoids you mentioned. So
I'll use it as the common ground.
While I've not seen this particularly curious behavior before, I do have
some suggestions and know where to find these settings in the text-based
config files as well, which should help as a last resort. I've had to
directly edit the config files myself for other issues, and now keep both
a backup copy and the operational copy set read-only when I'm not making
specific changes, so it can't be damaged. I'd suggest doing likewise, as
the file in question, while text, has a quite complex structure making it
not the easiest thing in the world to directly edit.
You clarified that widgets (also called plasmoids) are unlocked and that
other plasmoids, including other instances of one of the problematic
ones, show the floating config tabs on hover. Thanks. I agree, it's
very strange that some show the tabs but not others...
Unfortunately, other than toggling the locked state and restarting plasma-
desktop (presuming you have plasma set to desktop, otherwise plasma-
netbook, which I'm less familiar with) a few times in an effort to try to
get the config tabs back, I don't have any further suggestions to try on
that attack angle.
Which leaves three others I know of to try...
Simplest, if it works, and if it doesn't you should at least get a bit
more information about what's going on, at least with yawp, which I know
has this option. (Not sure about the stock plasmoids.) ...
With plasmoids on the desktop (as opposed to on a panel, where they don't
show the config tab either, so I'll assume yours are on the desktop, tho
you didn't say), with plasma unlocked, many plasmoids (including yawp)
have a context menu (traditionally displayed on right-click) with among
other things, a remove this <plasmoid> (remove this yawp, for yawp)
entry. The icon beside the entry should be a red X, for removal.
If you can see that on the context menu for the plasmoids in question,
hopefully that'll remove them. Please restart plasma (or logout/in to
restart it, or quit and restart X, or restart the computer) and verify
whether your changes held.
If not, please compare with the context menu where the config tab DOES
appear. Is that entry showing up there?
Since this option only shows up when widgets are unlocked, if it's
showing up on the one that shows the config tab but not the other one,
then the problem must be that the problem plasmoids aren't getting the
message that plasma is unlocked, for whatever reason.
If it's not showing up in either the plasmoids with the tab or the ones
without, then you're experiencing some other sort of plasmoid bug.
In either case, while a clue to the base problem, if that entry isn't
showing up, you can't remove the plasmoids that way, and will likely have
to resort to one of the other two, both of which are more intensive.
Option two is to configure a replacement activity and delete the current
activity containing the plasmoids you can't remove on their own. With
plasma unlocked, either context-click on the desktop (if you have
activities configured to show up in the desktop context menu) or click on
the desktop's toolbox icon and select activities. Add a new one, and add
plasmoids/widgets as desired. Switch to the new activity, then stop and
delete the old one. Again, restart plasma (or kde or logout/back-in or
restart X or restart the computer) and verify whether the changes held.
Meanwhile, the file where all this information is stored is $KDEHOME/
share/config/plasma-desktop-appletsrc. You can if you like try to edit
this file (with plasma shut down, of course), preferably after making a
backup, just in case, or simply delete it to start over with defaults.
WARNING!! This file contains nearly ALL significant plasma
configuration, including not only all plasmoids, but also all activities,
and all panels as well. Thus, deleting the file will delete all
customizations you've made not only to the one activity, but all other
activities you have configured, and all panel customizations you've made.
Unfortunately, that also means it's more difficult to edit by hand than
it should be, particularly because as becomes obvious rather quickly,
while like most of kde's config files it's ini-style plain-text, it's
obviously designed more for machine parsing than ease of human editing.
The format as mentioned is ini-style. [Section] entries on their own
lines demarked by , with setting=value pairs, again, each on their own
lines. In this case, however, we have [sections] [nested] [multiple]
[layers] [deep], some with [numbers] instead of human-readable
When editing, you have to figure out what component at what level the
numbers associate with, often by looking at what nested settings and
sections they contain to figure out what they are. For instance, I have
a section that includes this...
Obviously, everything within the multiple nested [Containments] 
[whatever] sections are individual settings and plasmoids with their own
settings, belonging to the activity I have that's named "plasmoids".
However, I have multiple monitors, and each monitor is its own "activity"
container, so [Containments]  is the "plasmoids" activity as well
(with its own activity=plasmoids setting), and I have to look at what
each one contains to determine which one corresponds to the plasmoids
activity on which monitor.
Unfortunately, plasma doesn't necessarily properly remove ALL the
settings corresponding to a component when that component is deleted. So
you're likely to find partial settings for components long deleted, which
only confuse when you're trying to figure out what mystery-numbers
correspond to what, and possibly trigger bugs in plasma, as well.
The main thing to ensure when you're editing the file, therefore, is that
you have the component you THINK you do (particularly when you have more
than one instance of a component, or had other instances in the past that
might not have been fully deleted), and that if you delete components by
hand, you delete ALL settings for that component, since there might be
several sections for plasmoids, and for panels/activities and other
containers, possibly MANY sections, pertaining to that component.
So... be sure you create a backup copy if you're going to try hand
editing, in case you screw up, and take it nice and slow.
Of course you can always delete the whole file and start over, but that
means you'll have to reconfigure all customizations from scratch,
including perhaps multiple panels and multiple activities, if you had
them configured. If you haven't customized that much, not a big deal.
If however, you're a heavy customizer as I am, losing all of them and
starting from scratch is something to be avoided if at all possible, even
if it means painstaking hand-editing of a config file as complicated as
this one is!
Hope it's helpful! =:^)
