QHY9m odd star shapes and lines

Hello all
I am getting some what looks like spikes in the brighter stars from my camera. They also appear to be a little bit squared off.
I didn't have the problem with my old QHY8pro so I am ruling out the scope.
I don't think I had the problem with just the QHY9 without the filter wheel.
So I am left with just the filters but I am not certain. I thought I may have over tightened the filters in the wheel causing some pinching but a checked the tension on them all and seemed fine.
Using a Tak 85,QHY9 (gain 23 offset 73)and baader 36mm LRGB in a QHYcfw2.
Any ideas?
Thank you
Jeremy
