This is how it evaluates what to grab, with a slight correction on that “preferred word score” is “custom format score”. https://wiki.servarr.com/lidarr/faq#how-are-possible-downloads-compared

So beyond quality, custom formats would be the greatest tool you could use to dictate that you’d want to score deluxe version lower that releases without deluxe in the name.

If you click the human icon in the activity queue you can see what release it thinks best matches what it grabbed, it could be possible that the release you grabbed isn’t on MB or the tags point to a different release.

When I add an artist the albums might show the giant multi disk tracklist but as soon as something is downloaded it picks a release that more closely matches what was downloaded. It’s not perfect always though but usually it’s not due to a mismatch in track numbers unless the release I have is not on MB

The release it “defaults” to should have no bearing on what it grabs though, it’s just what’s displayed until it grabs something and updates to the release that best matches the download.
