I would like to preface this by saying, I am a begginer to Unreal Engine.
I have been trying to set up real time motion capture using a handful of X-Box Kinects. The software I found which is able to produce live stream data to unreal engine is Brekel Body v3. I have been able to get the default “Brekel” Skeleton working with live link (using an animation blueprint) inside of Unreal Engine 4 and 5. However, I have not been able to correctly retarget the skeleton onto a different rig.
I followed serveral tutorials on retargetting in Unreal Engine 4, retargetting the default “Brekel” skeleton to the Unreal Mannequin. I used the retargetting manager to set the “Humanoid Rig” for both skeletons. However, the only bone that would move on the retargetted mannequin was the head. I noticed that the head was the only bone that shared the same name for the mannequin and the brekel skeleton.
So I found a mixamo rig with the same names for all of the bones as the brekel skeleton. Now all of the body parts move, but the retargetted model is extremely disfigured (see photos). This leads me to beleive that the live link plugin is somehow ignoring the retargetting process. Even after removing most of the bones from the hummanoid rig, all bones continued to move in a disfigured manner. I have attatched the project file below.

Is there something I am doing wrong in the retargetting process?
I am happy to provide any additional information.
