Emails on or before 1/28/18 on the image were attempted to be deleted. These email headers are grayed out and they are not selectable, copiable, movable or deletable. It does not matter if I use the Delete key on the keyboard, or "Move to Trash" button on the toolbar, the outcome is always the same. I tried updating the All Mail folder with no change in appearance. Curiously, this is not the case for Spam and Inbox folders, the messages there are normally deleted. Do you think Kmail intuitively knows that the messages in All Mail folder of Gmail accounts may never be actually deleted ;)?

I'm assuming that it's a IMAP account. Try this:

Settings -> Configure KMail -> Accounts -> (your account) -> Modify -> Advanced -> Automatically compress folders 

The names of the last three steps are translated by me back from German to English. I've started KMail in a terminal like this to get the English language: "LANG=C kmail". But this didn't work for the last three steps.

Hope it helps,
