Metahuman face proportions lost from identity creator to Metahuman online editor

Hi I am having a problem where I create a metahuman identity from a mesh, it does the identity solve and comes out pretty much one for one as the source model-particularly the head shape.

However when I go online to the Metahuman creator and go to work on the model, it looks quite a bit different than when I did the metahuman identity solve in Unreal.

Specifically the facial proportions and head shape are quite a bit different. I have seen other tutorial videos where this happens. I guess the makers of those videos weren’t worried about a 1:1 transfer, but that’s what I need. It still looks like a human face just not the same one.

How do I stop the facial proportions from changing when it goes from Unreal to the Metahuman creator?

Thanks
