Problem with animation blending

Hi. I have walking animation and crouch walking animation. The problem is, when blending those animations using the Inertialization node, it moves each hand a little bit. After the transition, hands go to the desired position. How can I fix that? Thanks

ps. I’m using edited lyra animations

Bleck_Crouch_Walk_Fwd.FBX (1.7 MB)
Bleck_Walk_Fwd.FBX (1.7 MB)

Removing intertialization fix the problem?
