MusicBee 3.2.6902, syncing to a Samsung Galaxy S9 on Android 9 with the following settings:
Music Files: Music\MP3\*
Playlists path: Music\Playlists
Each time I sync, everything goes where it's supposed to, *except* the very last playlist appears as a duplicate 0-byte file under the default "Playlists" directory at the root of the device storage.
For example, assuming I have playlist1, playlist2, playlist3. The result of the sync is:
Music\MP3\(all the music appears here, as expected)
Music\Playlists\(all the playlists appear here, as expected)
Playlists\playlist3 <---This is an additional 0-byte file that shouldn't be here.
