Adult Hair to Child Hair (Bald Head result)

I followed a YouTube tutorial to convert adult hair into child hair, the hair im converting is a CC item (hair for Anya Forger, which currently is only available for toddler and adult and I specifically want a child sim for Anya) so I followed the tutorial edited the item in blender and Sims 4 Studio, and when I import the mesh it shows up in TS4 Studio. When I try to load the game and put the item on the sim in CAS, instead the icon is a bald head (even if I try to upload a thumbnail.) 
I have tried this twice and I have the original CC file in the same folder as the adjusted file, however it will not show up past a bald head in icon, CAS, and in game.
