I imported from my iTunes library and got a lot of playlists that I've since removed, but I'm unable to delete the empty folders that were left behind. I've optimized and cleaned the database. The empty folders show up on certain clients but are hidden in others. They do not show up in Plex Web, which is where I would expect to go to delete them.
All blank items shouldn't exist:
Preferably, these folders would delete automatically once all their content has been deleted.
NOTE: This thread previously suggested this was an issue with the Apple TV client, which is where I discovered the bug. This is not the case since the problem persists across other devices. It seems to be a server issue.
