List Variables in ReportBuilder 5.0

I'm seeing bizarre behavior in ReportBuilder 5.0 with list variables and was wondering if anyone else is seeing the same thing. When I select a list variable, everything in the build of the query goes fine...but what gets returned is actually a list of states -- it looks to be from the standard Geo reporting. That same list1 variable works fine in Reports & Analytics and in Ad Hoc Analysis -- the values aren't remotely related to what is being returned through Report Builder. I tried it on another list variable and got the same result -- a list of states.

I've attached a screen cap.

Anyone else seeing that sort of behavior?
