How to prevent colliders animating between animation states? Also prevent rotation on x axis of blend tree.

Hi I'm animating 2d boxcolliders and when the animation ends the colliders jump out before the next animation due to the colliders adjusting their positions for the next animation, how can I make it so it changes instantly, rather than going from point a to b. Also the colliders rotate on the x axis during a blend tree state when the velocity of x is 0. Any solutions on how to prevent this will be greatly appreciated!
