Shoulder and arm bones changing position

Hi I am currently having an issue with deformation, after spending a few days tweaking and learning more I have noticed the bones are moving for the arm. i.e. clavicle, upperarm, lowerarm, etc… Below is an image of the bones in Blender.

If see see the clavicles location that is correct, but in the below image in Unreal Engine You can see the upperarm is where the clavicle is and roughly the same size.

Any Ideas as to the issue here? I have spent days watching how to videos and learning just to come up with the actual issue that was happening.

I have the same problem, importing from Blender and I set up the armature with Uefy and rigify. Did you ever figure out what was wrong?
