Molding settings not working, molding appearing where I don't want it?

HD 2026, Mac OS.

Trying to figure out why I'm getting molding where I don't want it. 

 

I'm looking at this wall construction here.  I want molding (tile) on the walls coming out from the sides of the room, but then no longer once it cuts in towards the door.  Right now the molding is appearing everywhere, and cutting off the windows behind the bench seating. 

 

I've looked into each wall, and where I want it, "no interior (or exterior) molding" is checked.  Yet it seems like HD is just generating molding regardless.  If I peer into the materials on those walls, no molding/tile appears.  And yet, it's rendered there.

 

Sanity check?  Something I'm doing wrong?  

 

 

 

Crude markup on the drawing:  green yes molding, red no molding.

Instead of using a molding, I'd recommend using the custom backsplash tool or a wall covering in the individual wall’s specification to achieve your desired result.

Ditto to above.

molding is meant for those cross section shapes in library to be "Extruded" around room.
