How to get metamix setup correctly

[Guido83]

I am trying to get metamix working. In a first instance I would like to add discogs as a second provider. Ther first one is currently "lidarr custom" poiting to the musicbrainz database on https://api.musicinfo.pro, as the default MB is currently broken.
But as soon as I add discogs, and I hit Refresh & Scan on an artist page it grbas albums from discogs as well. BUT it also adds albums from a completely different artist.

Let me give an example.
I refreshed the artist "Moby" (https://musicbrainz.org/artist/8970d868-0723-483b-a75b-51088913d3d4 and https://www.discogs.com/artist/1031-Moby)

After the resync has been completed there was also added the album "MIS-SHAPES 3" from the artist "swag" (https://www.discogs.com/release/20327959-Swag-MIS-SHAPES-3). I cannot find any relations between them. This is not the only wrong album which was added btw.

Am I setting it up wrong?

What is actually the Priority Rules setting. What is higher priority, lower or higher numbers?

You're right.
I can see this album too. I'm not sure where it came from, but I'll look into it when I have time. In Lidarr, lower numbers always mean higher priority.
