Detailed description of the problem It is not possible to edit a playlist regarding the tracks in it. Once a track is added, it cannot be removed as edits are not saved! Minimum number of steps to reproduce the problem Open MyAudio either via Tools Menu outside of a campaign or when Inside as GM Add a new playlist Add a track to said playlist either by choosing it from the list or uploading a track yourself Add a second one and close it (switch Page when outside campaign, close the popup when ingame) Added tracks are still there (INTENDED) Remove one of the tracks added before, Close and reopen BOTH Tracks are still there! EXPECTED : Only one of the 2 Tracks is there, the other is removed. Reality : Both Tracks are still there! Workaround DELETE Playlist completely and add it anew!
