I can understand that because you are creating a solid 3D wall you should really have a pen in cross-section around the fill.
The wierd thing is the very first time I saved the profile with no contour pen it worked and in section the wall had no line in section.
But try as I might now I can't repeat this.
A thin white pen might be as good as a wide dotted line as that shouldn't print if the pen colur remains white in your printing pen set.
