In-place sweep acting wonky

[patricks]

I have a wall with a sweep along the top of the wall (flat trim for a top cap). I'm trying to add an in-place sweep that goes around that top cap to create the bullnose edge. I used Pick 3D Edges, and after finishing the sweep it looks fine. But when I finish the in-place family the sweep pops down to some random location, even going down vertically along the end of one wall.

What the heck is going on here??

Dumb questions, but what happens if you try to add that profile to your wall family instead of using inplace?
Only thing I can think if is your path isn't correct. Or is it offset from the work plane? Are yo using a profile to create the sweep or are you doing it by sketch?
