Why are objects duplicated in state REACT?

Question

JavaScript

The essence of the problem: I somehow duplicated objects in state. For the 3rd day I have been re-reading all possible forums and I cannot find a similar problem.
ps Perhaps for someone it will be a very obvious mistake, since I'm just learning to program, I will be glad for any help.

It seems that you have already asked in chats, here maybe you registered the commentPage props where you passed the commenPage object, I think it’s a common mistake when writing.
