You don't have a problem Morton, I have seen this many times over the
years. As I said, the secondary holder has been twisted to the left by someone trying to loosen the central screw. If you look carefully at your last picture you will see that none of the vanes is perpendicular to the
secondary holder. The top vane for instance leans to the left.
If you put two Allen keys in the bottom two mirror adjusting screws, [the horizontal ones]hold them in place with one hand, and put a screwdriver or something similar between them, and turn the secondary holder to the right until the vanes are at perfect right angles to each other. You will probably have to do it several times, as the vanes will try to spring back a bit from the position you stop in. Shouldn't take you more than a few minutes. As I said before, the bottom two screws should end up parallel to the horizontal vanes.
