Playlist Duplicates

Hi,

I have an issues with PLS Music playlists and searching the forum implies I am the only one as I didn't find anybody else asking this question

Anyhow, I manage my music using MusicBee and maintain automatic / static playlists. These will be written to my local drive on save and sync'ed (copied) to my NAS automatically where Serviio is picking them up. This all works nicely, however, when the playlists get copied / overwritten on the NAS and Serviio picks up the changes, it yields duplicates of all copied playlists. Looking into the playlists shows, there is an old version and the new version of the playlist (that had music added for example).

Any trick I am missing?

Thanks for you help in advance

Kai
