Extra bone attached to the root

So I bought a character from the marketplace which stated it’s rigged to the epic skeleton. After attempting to assign it to my skeleton it’s come to my attention that there is an extra bone that exists prior to the root bone. Because this bone exists I cannot assign the character and accepting an offer to try and create the bone from UE4 it fails and crashes UE4.

I looked online and from what I can tell when this thing got exported as an FBX or whatever file it is the software creates an “armature bone” before the root bone.

Does anyone know of a way I can get this skeleton to assign to the epic skeleton please? I simply don’t know enough about UE4 to know whether there are options for me.

you would have to export the asset, work on it, and re import it.
you can try to use retargeting insread…
