From looking at the photos, it almost looks like maybe that part can rotate. If that is possible, you might be able to fix this pretty easy.
If this isn’t possible, it isn’t too hard to remove and turn everything to make it right. We had the issue of the mounting screws rusting from under the wall mount brackets, and I replaced the screws with stainless steel screws. The covers can slide off of the top and bottom brackets exposing where the screws are. Just thought I should edit this post with photos of the covers removed, which I used a thin putty knife to get them started.
