It was driving me crazy so I went back out in the garage and riveted the errant rib back into place. If you missed the previous episode, I mixed up one of my left wing ribs with a right wing rib and long story short, I had to remove it from the left wing and rivet the corret one into place. It's the 5th rib from the root of the wing. Went well - no issues. Now I can turn my attention to the right wing skeleton.
