Shape optimization on loaded knee (L-sock)

I'm doing shape optimization on the loaded knee. I've made the geometry similar to the image posted, instead I've just put a fixed constraint on the upper boundary and the force is working in the -y direction instead. I've made the geometry by creating two rectangles and using the difference tool. I've also added a fillet with radius=5.
I'm using the Deformed Geomtry module in order to make the shape optimization. I've attached my module, so you can see the Prescribed Mesh Displacements. I'm using the total elastic strain energy as my objective function
My problem is that shape optimization doesn't work properly, I want my result to look something like result.png (attached), but instead it looks like result2.png
I hope you can help!
