I dunno if I messed up somehow or not. I've been playing around with LXDE and XFCE Desktops. I then jumped back into KDE, which is my main desktop environment.
I clicked on he start menu and discovered that a lot of the sub-folders are missing. For instance, when I go to the Games category, games ar enow scattered. Gone are the sub-folders for card games, board games, etc. The menu pops up and takes up he entire screen.
Same thing for other Menu entries. Under Multimedia, gone are the video and audio sub folders.
I'm not sure if this is due to a recent update or jumping in and out of DEs. I did not edit the Start Menu in any way.
