Should my chin have a double bump with a chin implant? (photos)

I received a chin implant 2 years. He recommended a large implant, but it seemed too big for my face. I went back removed it and replaced it with a medium chin implant instead. Both had a weird double bump profile look. I’m not sure if I need to receive filler to fix it or if it should be removed entirely. I was recommended a chin implant due to my weak chin and from complications involving a TMJ jaw surgery. Why does it look like a double bump? How can I fix it?
