So I watched it from the roof using my One Control app(which does not stay connected).
As it is coming up the arm does twist a bit. Remember there is a fair amount of weight the motor is dragging up so it is nothing extreme. Just enough to twist the cap some to hit the vertical support and keep it from closing.
Bright idea was to see what happens if I squeeze a shim under the cap. I put it in and could not get it to act up. The shim is located at the furthest outboard I could get it, it does not hit the vertical support. Left it in place over night and figured I would get a plastic one, paint it black and secure in place with some sealant sometime in the future.
This morning I was wondering if I just stop the awning momentarily right before it hits and then finish the retract the twist should release since the motor is stopped. Popped the shim out and it worked. Tried extending further and tried no stopping right at the end and it would not fail.
At least I know now a shim will do the trick if it continues to act up. As I said though, I just hits barely but enough to stop it and it is not the fabric rolling up cockeyed.
