Model animating with backward rotation

I've got a model from the Unity asset store, but it appears to be rotated backward. All animations play facing the opposite direction to movement. I've tried different AI controllers with the same result. Changing the transform rotation doesn't solve the problem since it adjusts automatically. Putting it in a parent holder object didn't help either. All other models I've used before worked correctly, so after some googling it seems like maybe this was set up wrong in whichever program was used to create it. Being unfamiliar with that software, what would be the easiest way to fix this?
