do you divide the mesh one time and than project it?
or did you divided it multiple times and than tried to project it?

it makes alot of difference between those two

Your issue is that your original mesh is actually sharp instead of looking sharp.
It's essentially a bad hard edge across the multple hard edges.

Do you need them to be THAT sharp?  Can you run a small Deformation>Polish operation on it?
