Even if I change the title, it reverts to the state before the change

[Minako Go]

I am writing a sentence with Confluence, but even if I change the title and press save, it returns to the title even if I added it at the beginning title.
Please tell me how to avoid it

@Minako Go Are you editing the page, but not republishing it? The changes you make while editing are not visible on the page in View mode until you republish.

Could you add screenshots so we might have a better understanding of what is happening?
