Summary	0018774: Empty parent playlists fail to sync via USB (regression MMA)
Description	Setup a new playlist (empty) with a new playlist nested under it with 1 file and selected both for Sync. Neither shows on device after Sync. A similar instance of this may be: https://www.mediamonkey.com/forum/viewtopic.php?t=101217
Steps To Reproduce	1 Create new Playlist 2 Create new Playlist as child Playlist of first Playlist 3 Add 1 file to child Playlist (none were added to parent Playlist) 4 Enable both new Playlists to be Synced 5 Start USB Sync --> Expect both Playlists on device, but neither syncs (3 attempts) If the parent Playlist does have a media file on it, USB Sync successfully Syncs it, so it seems to fail with no media files on the parent Playlist. (Sync also suggest a bunch of files to Sync Device > PC, but all these files were Synced by MMW and still in MMW).

So it seems a regression in MMA (tested 1.4.5.0960), assigned to Martin to look into it. image.png (6,620 bytes) image.png (6,620 bytes)
