Blender to UE4, Skeletal mesh issue - Bones Snapping to Parent. HELP!

Hi guys!

I’m having an issue in regards to importing a skeletal mesh from Blender to UE4.
The issue is that the bones are all snapping to the parent bone.
I’ve tried using various exporting tools, and checking/unchecking various options but am at a loss as to how to correct this issue.
I have changed the skeletal relations from “Animation” to Skeleton in the UE4 skeleton tree,
I have searched high and low for an answer, I need these bones to be in their original position rather than snapped back to the parent bone.

Thank you for your time. I would really appreciate any assistance.
