I was thinking about it over night and I think I know what happened.

I checked the ribs before I glued them to the bottom spar, the TE bottom the top spar and the TE stick. I think when I put the tube in I bowed it slightly somehow. I know the tube was a tight fit, I had to twist it in.

I'm going to try putting some debonder on the tub at that rib and see if I can push it on more and straighten it out.
