Hatch Material Missing in Elevation

[BomberAIA]

I made a wall type with a siding as a finish on the exterior. It does not appear in the elevation view but does in 3D. It is not hidden in the view and I can't find the problem. The roof material shows up but not the siding. Am I missing something?

post the family. We'll try it on our machines.

Is it a model pattern or a drafting?

I sometimes get this.

Sometimes the printed version is fine but the on screen version is not.
