I use Jellyfin for my music collection, and sometimes the album artist and artist fields for the same artist will be populated slightly differently. For instance, I have one case where there are three different ways using &, 'and' and +. I have removed these from my library, updating them with manually with MusicBrainz Picard to use the same spelling, and reuploaded them to my server. However, it uses the old metadata still.

Is there a way to efficiently reset metadata for only certain albums so that these three instances are merged and I can access all three albums from the same album artist?

EDIT: So I managed to get this working now. What worked in the end (unsure if all steps are necessary) was to remove all the files from the server, run a rescan, delete all the albums (they would still be in Jellyfin with a blurred album cover), rescan again, and now the artists would be gone. When I added the albums again, the new metadata would be used.
