Mono slab problem

[amddrafting]

See the attached...

I have a mono slab situation, which I am absolutely ecstatic about the new feature by the way, the problem is that the wall on the side is correct but notice that my slab is extending to the outside of the wall at the front of the house. I can't get it to match the side wall. I've verified that the "Foundation to this line" is checked on the wall specs dbx. I've tried a bunch of options to no avail.

I'm actually amazed that I got it work with a basement. I'm liking this, just a dumb little glitch I can't figure out... any suggestions?
