Unable to import Animations "Root Track Error"

Hello Everyone,

I’m moving my project from Unity to Unreal 4 and one of the biggest issues I’m having is importing animations. I’ve followed the guidlines using a mixamo skeleton to import them, but A lot of them recieve a Root Track error (Root is found in the Hip bone but animation does not contain a root track). Is there any way to fix this so that I wont have to bay hundreds for pure Mixamo animations? Is there any alternative animations that work with the Mixamo rig?
