I attempted to "fix" mine. I have completely removed it now.
The problem is that the way the LPR is made, it only lines up with the screw holes in my tag (top or bottom) if the tag is set into the groove on the back of the LPR. That means that the LPR adds about 1/4" of height to the tag, whether it's on the top or bottom. With the LPR on top, it was barely rubbing on my tailgate, and only does so just when the tailgate gets to being 100% open. With the LPR on top, my tag is sitting all the way, so the bottom of the tag is resting on the bumper itself. In other words, it cannot go any lower. So, there is no way to mount the LPR on the top of my tag where it won't rub.
And if I put it on the bottom of the tag, I have 2 problems. One, with the LPR holes lined up with the bottom tag holes, it pushes the tag itself up about 1/4" from resting on the bumper. That means that the holes in the top of the tag no longer line up with the screw holes in the bumper. And, two, I didn't actually check, but I would expect that, since that much extra height caused the LPR to rub the tailgate, the top of the tag would rub against the tailgate.
At this point, I don't see any feasible way to use the LPR as it is currently designed. What I think they need to do is mill down the top of the LPR so that it does not extend above the top of the tag at all. It is an unfortunate and poor design choice that they made that results in the LPR adding 1/4" or so of extra height to the license plate. I suspect it would work fine on many vehicles. But, it does not work on my truck.
