I am working on a freebie that I had never tested in Studio and would like to help this person out if possible. With the figure there is a known issues with normals not facing forward in Poser. The fix was easy but looks like it has resurfaced in Studio. Is there a way to fix it?

That loks like a double surface. The best fix would be to remove the inner layer of polygons (if thet were added to avoid a see-through inside in Poser it would be better to use the Normals forward setting for the surface in the Material room instead of adding mesh). An alternative would be to apply a white image to the displacement channel in the DS Surfaces palette with a very low strength so that the surfaces get pulled apart ractionally when rendered.
