When I remove a track from a playlist on the Prime 4 unit itself, it is removed as intended. If I then remove the SD the next day to add a couple of new downloaded tracks & reinsert into P4, the tracks I removed from the playlist earlier, reappear in that playlist. This has happened since 2.0.2.
If you have connected your external drive to Engine DJ on your computer and have transferred new tracks or used Sync manager, yes, this is what you wrote. It is a known bug.
Thanks @DjAj - that is the issue I have, yes. At least I know it’s a bug. Thanks for letting me know.
