I have an album by a band called PROMISES, all meta data within the files are correctly naming the band as PROMISES, however Roon insists on calling the band THE PROMISE.
For an album, you could just mark all tracks and then edit it once for all tracks.
Another question: does Roon know the artist and has the name wrong? Because you could - alternatively - change the artist (group) name to what you want it to be.
When I edit the individual tracks there is no option to change the primary artist name that I can see. When I first added the album Roon had the album name PROMISES and the Artist name as THE PROMISE, until I changed the primary artist in the album. So it shows correctly at the top, it just insists on putting the ALL TRACKS PERFORMED BY THE PROMISE there as well.
