Animation acting weird when targeting it to my skeleton:

So i tried to target the Pistol Animset to my skeleton, but the skeleton is starting to float in the air. I guess it is moving with the root-motion? I don’t know what i do wrong. Exactly same thing happened with the Mixamo animations. I just cannot disable the Root-motion, no matter what i do.

Here is the video:

Any idea how to fix this? I don’t know if there something wrong with my skeleton, starting to think so… Weird.
