My local playlists are spontanious moved over to Qobuz

Does anyone know why my local playlists are moved over to Qobuz without me doing anything ?

what I do is the following : I create a playlist name
Next I select songs from my local library and add them to that playlist.
later ( don’t know how long it took weeks, months ? ) my playlists are marked as a Qobuz playlist.
My local library is no longer connected to that playlist anymore.
Very nice to have that playlist when I’m on the road but not all the songs I have in my local library are on Qobuz.
Next to that I just want to have control over what I create

Do I need to set something in Roon to stop this from happening ?

Thanks for your support Hans
