I have two releases in one release group. But only one is correctly assigned. How can I change the release group for the other?
Here is the release group: https://musicbrainz.org/release-group/a2da2422-e462-4fef-b3be-d831bc8c122c
The promo release is completly different (it includes only some tracks) of the released album. The album release includes the tracks of the promo EPs “Amerika Evropa” and "My Girlfriend Went to Maroc.
