Fusion360 Mach3 Turn Post

So as all most know, there is no real mach3 turn post from fusion, it's told to use the generic fanuc post, I have several user modified posts as well, one is better. BUT I still get this strange looking model in mach3, and it shows on the part machined.
Anyone have any ideas on what could cause this?

BTW what your looking at is the radius on the left side, it looks good on the chamfer but the radius is stepped...
