Lower body animation not playing

Hi, I was experimenting with humanoid rig in this one project and is it possible that it messed up my project's animations?

Right now, it seems that the legs or bottom parts of the animation isn't playing in the editor/scene and animation file preview. It is only when I animate the rigged model in my 3d software and import it into unity that the animation works fine but if I plugged in another different character with the same rig, the bottom part of the animation won't play.
