Model does not play animation

I imported the maze element Ice Golem from the assets store found here https://www.assetstore.unity3d.com/en/#!/content/3746

Then I created an avatar for it from the rig option once it was imported and unity gives me the check saying that it worked fine. But when I use that avatar in an animator controller the model is just forced into a kneeling position no matter what animation is playing in the controller. I am not getting any errors at all and have nothing else what so ever in the project.

Sorry if this is a simple question I'm pretty new to animations in unity
