Can't get showAllDiscs=true to work

There would be no problem if all tracks of the album have the same artist. In this case, you would select Artist > the artist name > n albums > your chosen album. If you are doing this and getting the screenshot you posted, there must be at least one track of the album Celebration2 that doesn't have Madonna as a tagged artist.

What are the exact browsing steps you are using to end up with the screenshot you posted?
