Double crease or extra skin in cleavage area after BA. Would a wider implant fix this? (Photos)

I am 6 months post op. 5’10, 148 pounds. I have 375 Natrelle High Profile. Around 3 months post op, this area of skin in my cleavage started showing up and this is what it looks like now. It goes away when I lift my arms, but it feels like a fold of skin? How can this be fixed? Would a wider implant be better for my wider chest instead of high profile? Are the implants too narrow? Should I change to a moderate profile or does this need fixed in another way? Thank you.
