Why is my mulled fixed window called HL (hinge left) in schedule?

[GeneDavis]

My default window for the plan is a single casement, hinge left.

 

I place two fixed windows in position, the upper considered a transom window, open the spec dialog, and because each component is a fixed window, the hinging is grayed out and not applicable.

 

I mull the two to make one joined unit, and the hinging in the dbx is grayed out and not applicable.

 

But in the window schedule, the unit is called out as HL.  Why?

If I were to guess, it seems Mulled units look to Windows Defaults for their schedule info.

Go into Window Defaults and change it to Fixed and see if that fixes it, it did for me.
