Change email account "The current password is incorrect"

I try to change my email account to another on Replit. But I get “The current password is incorrect” in the Password Confirmation box. I login with Github. So I tried my Github’s password, my password’s Replit account and Gmail account. But it doesn’t work.

Why? What password “Password Confirmation” refers to?

You tried the current email on your account’s password, right?
