That's because that is what your source is, 5.1.
Typically what I have seen on receivers is that they will show boxes to represent the signal but only show text in the boxes of the speakers that are actually present. This will depend on the manufacturer though.
However, if you have your speakers turned off in the menu...its working fine. ESPECIALLY, if you can hear voices. In movies especially, if you were missing the center channel you would pretty much hear nothing in terms of voices.
