Differential pairs not recognized in Constraint Manager

I have a board with several differential signals. When I opened the Xpedition Constraint manager I noticed that Xpedition does not recognize some of the differential signals. See below. You can see the that SOME signals are recognized as differential while others are not, even though they have the same naming convention. The blue icons to the left of the signal show the differential signals as they should be. The red circled signals are differential signals, but the constraint manager only recognizes them as single ended signals. The issue is, when they are recognized as single ended signals, I am unable to couple them when routing.
