Music library scans/adds xtra artists

Hi there i hav v20.5 running on my shield and almost everything is perfect,but when i scan my muxic folder on my syno nas  kodi adds al kind of artists that aren’t in my music folder but on or in the albums where its a cooperation with the artists in my music folders
I have my music folder setup as /DATA/muziek/xxx(artist) and then the albums from that artist
I dl all my music with lidarr running in a container.
After a scan of the library i get all those random artists added to the library in kodi but they do not show up on my nas.
How can i let kodi scan for just the artists that are in my music folder?
