How do you make a SKM_Quinn walk for an animation not game? MF_Walk_Fwd not working

I am VERY new to UE and any 3D design. I am following a very basic tutorial on how to create a brief animation of a landscape with the provided female mannequin. All I’m trying to do is get the mannequin to walk rather than float. I added the “MF_Walk_Fwd” animation after creating keyframes to get the SKM_Quinn to move but it is still floating and not walking. I did expand the MF_Walk_Fwd bar to encompass all the frames in the animation.

The tutorial I am watching is this: - YouTube (48:19 is the part for animating)

I followed these steps but it isn’t working. Is there an easy fix or is this more complicated?
