Not surprising, it is far from obvious.

OK, yes, the Tag Manager manipulates the list of tags in the database.
It does not directly affect the images.

From the Tags Manager window, use the 'Sync Export' dropdown and use
'Write tags from database to image' although I am not 100% confident
that this will remove tags from the images that you deleted from the
database, but in theory I think it should.
The other tool you can use is in Tools->Maintenance and sync the
database to the images.
Both of the above options seem rather heavy weight to me and liable to
touch more files than they need to.
The way I would use however does not involve the Tags Manager tool at
all. Click on the Tags icon in the left sidebar, then select the tag you
wish to delete. This should show you all the images that have that tag
applied to them. Select all visible images with Ctrl-A. Un-tick the
relevant tag in the tags area on the right. Click 'Apply' in the tags
area. Right click the tag in the tags area on the right and select
'Delete tag'. This way you know that you are removing the tag from all
relevant images and then removing it from the database.
