Not sure if this is a bug or what but the grids in back and front views are not at the same position on both views on PGA#18. There’s an offset of 1/2 square grid positioning on the back view. The aimer haven’t been moved at all.

I'm guessing what you're seeing there is because of the parallax difference between the 2 camera views. The 2 cameras are not perfectly in line with each other. They are offset somewhat.
