Albums by DB's don't show up

[jhs39 13]

I have two albums by the DB's that show up in the Media Browser web client under album artist.  But when I click on the corresponding artist in Media Centre on Roku the albums cannot be found--I just get the searching indicator.  I don't have this problem with any other artist as far as I know--usually if there is a problem with no albums showing up in Roku Media Centre then the same problem is occurring in Media Browser and once I fix it there the problem is also fixed in Media Centre--but in this case there doesn't seem to be anything to fix.  Can anyone help?
