Ram Elements 2D Truss Analysis

I have an existing roof truss with double angles.  Most of the double angles are SLBB.  The truss is modeled in the X-Y plane and all of the double angles have the local 3-3 axis perpendicular to the truss.  The top and bottom chords are modeled as continuous members. All of my loads are gravity loads -Y.

Why does the Ram Analysis and Design reports show values other than zero for M22 and show zero for M33 moments?  Isn't this backward?  There should be no out-of-plane moments.
