Question How do you keep Mixamo animations from moving the character it's attached to?

I'm building a 2.5D game in Unity, and I'm using the x and y axes for player motion, while the z axis is purely for environmental assets. The character controller was working pretty well, so I decided to add animations to the mix.

The Mixamo animations, however, make the character's movement stop working properly. If I go back and forth, the player model will start to move upwards on the Y axis and twist on the z axis so that it's moving off of the platform. I imported the second jogging animation with "in place" and "without skin" selected.

Since I'm not using the z axis, I tried resetting the z-position to zero every frame, but the animation will still override that.
