Curtain Wall Bug?

[DGSketcher]

I thought I would use the curtain wall object to create a patent glazing roof, which was going well in 3D and the elevations but when I switch to the floor plan view rather than the expected full view (as set in MVO) I get schematic lines below the storey cut but full size transom/frame cuts. I get this whatever the roof pitch.

Can someone more familiar with the curtain wall tool advise if this is normal for inclined panels?

Solved: Floor plan display settings in UKI template set to "Symbolic with overhead". Changed to "Projected", now displaying as expected.
