Mine does the exact same thing, although it's hard to tell if it's to that extent.

One thing I did read from a guy who sells these kits on another forum, and it's hard to tell from your pics/video, is that the nut closest to the eyelet should be cinched up tight against the eyelet. At that point the last thing to tighten up would be the bolt on the other side of the bracket.

When I tightened this last nut it actually pulled the bracket in toward the eyelet.

If I remember, it was contradicting to the instructions but made sense when done.

The other part of importance was to make sure the eyelet was nice and centered on the ball, which it appears from your pics, you've done.
