Tool paths say circles OF cuts ovals?

So I designed a very basic donut shape with legs in carbide create the free version, when I set my OF woodworker going it doesn’t ask me to probe Z but i do manually anyway. Then when it cuts all the aspects are off, the circles become ovals and everything looks at little squished??

Quickest fix ever thank you!!
