Wall Sweep Won't Clean

[wyatt.johnson.architecture618816]

All,

This one is throwing me for a loop, I have a simple wall with a mitered corner and a wall sweep on the top and bottom. Neither wall sweep is integral to the wall both are applied. I have checked and the ends are in the right place, but the wall sweep at the base of the wall will not clean up. I have attached an image that should hopefully make sense of it all.
