Well, I believe that I see something amiss. Now, it could be just the way you held your camera but when I magnify your picture, it appears that your mast step is not in line with the center line of the boat. I believe that the rear of the step is biased a bit to starboard and the front is pointing a bit to port. Next time you're at the boat, I would verify that the mast is plumb and square.
It's not a complicated fix but it will require the mast to come down and I can tell you from experience that the bolts that hold the plate to the compression post are a bear to access in the space available. FWIW, my compression post (inside the cabin) was shifted forward by almost an inch when I bought Waffle House. So while tending to that, I also went ahead and installed a halyard plate and a newer style mast step while I was at it. Let us know what you decide to do. I hope this helps.
