Unmerge Artists help?

Hi I have managed to merge two artists with the same name into one and it’s using the wrong bio now for my album. How can I unmerge them? Deleting the album and adding it does not appear to help. It always has a bio from the other artist.

Setting-Library-Unmerge artists should bring up a list of merged artists that you can unmerge.

Thanks will give that a go.

Now it appears Roon has this album under both acts so their metadata is borked. Will ticket it.
