Well, I add brushes in my brushes folder -> they don't show. Not always but sometimes.
Alternatively I delete subfolders from my brushes folder because I don't need them any more
Sometimes works, sometimes does not work, is strange.
Where do you add your folders? Should be your home folder ~/.gimp-2.8/brushes Have you checked for duplicated entries?
Do you have any extra folder entries in Edit -> Preferences -> Folders -> Brushes.
This is the default, just two locations. Sub-folders will register, no need to add them.
