Gap in wall material region at doorway

[Straight_Line]

I can't figure out how to solve this issue of the gap appearing in my tile wall material region. The custom backsplash I created crosses over a doorway I placed in order to create an arched opening between two rooms.

At times like this, so you don't get frustrated, I'd throw a solid in that gap, put it to the thickness of your tile, and the same layer.  Sometimes doors and invisible walls do this, and sometimes they don't.
