Curved Wall Window Bug

[MSotero]

I believe this is a bug as it only happens in curved walls.
Set the Casing Trim Thk...... parameter to "Off" and the head and jamb extensions produce what you see in the attached image.
However, make the Wall straight instead of curved and things are fine.
This is done with W1 Casement for AC10. Maybe all the Windows do this?

Turning off the exterior trim produces this error.
Again, just if the Wall is curved.
