When we put a release on right pane it is usually to match files with its tracks.
When we click Scan, the matching tracks are from other releases which use the same recordings instead of the release that's already loaded in right pane.
I mean it should prefer already loaded release if it's the same recording, no need to load a new release.
Usually we want the one we specifically loaded.
The more I write the less understandable it is. :/
