I don't think it's an adjustment problem. Your hitch is well made and has less "slop" than some hitches. Your solution is to uncouple with the ball perfectly centered in the hitch. If you backed into the site, the ball is hanging up on the front of the coupler. Likewise, if you're in a pull-through, it's hanging up on the rear side of the coupler.
To center the ball, chock your TT wheels on both sides. Release the coupling lock and raise the tongue 6" using the jack. If the ball doesn't drop free, attempt to push the trailer (two-person job) back or forward a bit (it doesn't take much movement). If you can't do that, put the TV in neutral and release the brake. Either of these should result in the ball dropping from the coupler. Works every time for me. I also grease my hitch ball (but that's another whole discussion).
