Looks like you have an album considered as a “compilation” or" sampler." You will likely have to make sure that the album artist tag in the embedded information is set to “Various Artists” You can leave the track artist as it is.
As well, make sure ALL of your compilation albums have the album artist tag set, or you’ll run into more problems at some point in time. You’ll probably need to refresh the metadata, and might have to Plex Dance any of the affected albums.
