How to remove solid window fill

[JMSarch]

I can not figure out how to remove the solid white fill from doors and windows I'm trying to move to a Demo class.

I tried changing the Demo class fill to none and all window component classes to <window class> but no luck? Also tried different combinations of classes and still always has a solid white fill? Changing to a clerestory unit has a fill as well?

 

Anyone know how to resolve this?

Might you be able to post your file here so others can have a look at it?

 

Giving a fresh window’s glazing a clear texture is quite easy, but since you’ve already adjusted many things in your file it would be safer to advise based on what you have now.
