Strange behavior with animation

I have two animations. “Idle” and “Shooting”. If enemy is near then “Shooting” is true, Else is false and “Idle” is true. Both have same configuration, but “Idle” has a strange behavior.

Why this happen. How can i fix it. [Animations and model are from mixamo]. I hope you can help me, thanks

Solved. I leave the answer in case someone needs it

I had to change “None (Motion)” to “Idle”.
