Am I doing something wrong my flattener?

Hey guys, new bit of gear, and a new problem
I have a WO P-Flat 4 for my ED80. Not enough inwards travel to work with the QHY9, but works fine with the QHY10. I set up and pointed at the LMC, hoping to randomly find an area with lots of stars. Placed a good star in the corner of the frame and adjusted the flattener in both directions, re-focusing every time, and found a point where the star looked pretty round. Thought I was done and got excited, but noticed that the other 3 corners were terrible.

Any ideas on why, or what to do?
