primary moment error when using TempVar

When we using TempVar, RM Bridge V8i is printing its primary moment as TB0, not the TB in loadset.  The correct one is TB in theory.  Test a simple 2D 2-span continuous girder model.  Primary stress is OK but still a single stress check point doesnt express a stress jump at the temperature border.  see attachments.  maybe there is error in displacement but i didnt check.
