Ps4, square button is stuck in half, what can you do about it?

As can be seen above my square button is stuck (half). That said, I can still push it all the way through, but in games where I have to estimate the time it takes to press, it's pretty annoying. I have also removed the controller twice and put the button in again, but that didn't work. It would be great if someone could help me.

Classic case, new buying.

Expand and see what the error is?!

New ones are needed.

I already wrote above that I have already removed it 2 times and it still hasn't gotten any better.
