Like the title says, if I load a song that already has Musicbrainz information and I use the “Update metadata from existing Musicbrainz id or release id”, the mood field in the changes tab has the already present mood duplicated and appears to be really stored in the file when saving.
Desired behavior would be to de-duplicate the field I guess.
Below is a screenshot of a loaded and than updated song. As you can see it already has duplicate tags from prior updates.
