OK, I must be the only person on the planet that uses one surround back in the center.
Apparently Outlaw either didn't allow for that in their auto setup or they assume nobody does that.
I didn't think I would have a reason to set my surround back to "none" when I actually had one.

I don't see where that is addressed anywhere in the manual but after setting up all the speakers in auto mode, I was able to go back and set up the rear back manually.

Very confusing and frustrating but it's finally solved.

Thanks for the help Reet.
