Punching blending with idle?

Okay i’m trying to play two montages at once. One montage is for upper body (punching) and the other is for lower body so when punching while not walking idle animation does not play. I have it separated between two slots in AnimBP. My problem is that only one fires cancelling the other one. Any help would be appreciated. Thank you.

You can check the animation blending node, where you can specify the bone name, therefor the upper body will play the punching animation while the lower part will be idle
