Character controller and animation conflicting

hi, I'm having a problem with any animation that has my character lower the pelvis bone y position, crouching or something like that. Instead of the charcter going lower the feet get brought up and the characters upper body doesn't move. I think this is due to my characters controllers Collison box not letting it go lower but I dont know why this would be the case since the component is on the character as a whole not the pelvis bone. Also I currently am using many of the variable from the character controll for my movement system I can't not have it.
How can I have both the animation look how it should while also having a character controller?

 

you can do that in OnAnimatorIK with animator.rootPosition.y change, if I remember correctly. (that is workin, but moving xz seems buggy)
