IK Poles freaking out

so I have this issue with umotion pro. I have this animation that plays perfectly fine outside of Umotion but when I import the clip to Umotion and convert it to IK the IK poles go crazy as in weird rotations and positions,

sometimes rapidly, sometimes slowly

this happens 90% of the time with any animations I import, custom, or from Mixamo.

please help 

in this case at the moment its the legs

(this is more of a calm situation sometimes it's like 100 miles per hour all over the place flickering)

but the original animation when not imported into Umotion does not have this issue
