Make sure the bollts still go into the wing block and spar tube cleanly the holes may have wallowed out
Yes, I would suggest that you take the wing bolts out and see if the wing will slide on flush. If it does, then you need to replace the carbon fiber strap that holds the wing on with a new one, and/or redrill it so that the wings are snug when the bolt is in.

There was a problem with the Kingcat wings going all the way on in front, but leaving a 1/8" to 1/4" gap in back. This was due to a jig alignment problem when the wings were built. There was an AD that dealt with that, but it could also happen if you did install the booms correctly. On two of the Kingcats I built, I had to sand the front of the wing down a bit so that the wing would snug up straight against the booms...
