How to correct joint Movement Animset Pro

I recently bought the Movement Animset Pro which said all the animations are baked onto the Epic Starter Skeleton. The only problem is that there are weird gaps in some of the joints like in the picture. This stretches any models I rig using the Epic’s A.R.T. toolset in Maya. The distortion is just on a few noticeable joints. I’ve read all the documentation but I can’t seem to find a way to move the joints in the editor and save it so it updates with the animations. Offsetting the Mannequin in Maya to match the offset in animations just seems to make the problem worse. Any tips or advice would be greatly appreciated.

You may want to try retargeting as described here: Animation Retargeting (Different Skeletons) | Unreal Engine Documentation

You should be able to retarget all of the animations to your differently sized skeleton pretty easily.
