Importing Animation Problems

   Hello guys, my team and I are having problems with the animation of the model we made in blender. The animation deforms when we try to play it in jmonkey but the animation is okay when we play in blender. We have downloaded multiple models in and all of them deform as well. Except one, We imported it into jmonkey and the animation was okay.

  Can you guys please tell us what we did wrong in our model? We have followed the steps in these guides but it didn't change anything.

Could it be because we directly imported the .blend file into jmonkey? Or did we do something wrong while making our model?

This is our model Dropbox - new model.blend - Simplify your life
