Why are these (curved) faces not merging?

Hopefully quick question that I want to sort out now before it comes back to bite me down the road.

I'm designing this enclosure with concave/convex back/front faces, and it will be injection molded, so I've applied draft to the overall shape prior to shelling.  I added the feature "connector pedestal" to transition into the panel mount flange of a connector, but on the back (concave) face, the two faces have not merged into one.  I can't figure out why not, and if I Measure the edges of a sectioned view it says "the selected items intersect", but it does not list any angle between them or state if they are parallel.

Any suggestions?

Thanks
