Adding sketch entity results in multiple bodies?

I have a sketch that I was able to fillet correctly, but when I added another entity SW now says I can't do it because the new feature is a different body. When I try to make a separate fillet for it, it acts like it's not attached to the bottom section, and the fillets go "under" the part. I've never seen this before and I've added to sketches in the past. Any ideas?

The entity added is the one with the dimension on it.
