FBX animation import from blender squishing issue.

I have a model In blender which I imported into Unity. From there, I saved different versions of the mesh with different animations. the first two i did, "Idle" and "run" work fine. But any new ones I try to import in FBX format, (which idle and run were in) then it completely scrunches up my mesh, and the camera zooms in on the foot, and won't leave.

I don't know how else to describe this, so I'm just going to go ahead and put up this video which demonstrates the model scrunch up part. it takes a little bit to get to that point, but it shows the steps I took to set up the anim.

Thank you in advance for any and all help.
