Duplicated Animations When Importing From Blender

When using the UE4 to Rigify addon for Blender, and I export an animation using the steps described in the official tutorial videos, I end up importing two identical animations from the exported FBX file. One has ‘root’ in the name and the other has ‘rig’ in it. For reference, I’m using UE to Rigify with the UE4 mannequin, taken from the third person game template.

How do I prevent it, so I only import one animation, and which one should I try to keep for my project?
