Can't change my world's name

The character limit for a world’s name is 30, and my world’s name reaches 28 characters. But when I make a copy of it, it shows “(1)”, adding 4 more characters, therefore my world’s name has reached 30 characters and won’t let me add more (which is logic), but it won’t let me remove characters and this is the issue i’m reporting, therefore i had to deal with having a world’s name I don’t want to have.

Everytime I make a copy of the world, I have to deal with having the same name even though I want to change it. It shows (2), (3), (4), (5)… and so on and it’s honestly annoying for me.
