Character morph with different arm length - Animation problem

I’m using a genesis 3 character from Daz Studio with a female morph. The problem is that the female character has a different arm lenght. The moprph works fine in T-Pose but once i start using animations the hands deform in a weird way. I think it’s because the skeleton doesnt fit to the mesh anymore. In Daz Studio everything works fine. Is there a way to make it work in UE4?

I hope someone can help me here.
