I've only noticed this last night after updating the software. When I use the rulers 0 to 720 degrees. Zero is on the left hand side and the right hand side ruler is 720, but 180 degrees is on the right side followed by 240, 360 amd 540. Now I can move the rulers left and right crossing them over each other and this makes no difference. I've looked into the menu and tried custom settings and that also makes no difference.

Please advise...
