GPG account displaying

It’s my new account and e-mail. I created GPG key and added in account settings, after created signed commit and GitHub displaying another account name in signed, but redirection is to my account.

[Commit](Initialized composer · nikodemnzw/security-headers@149abe1 · GitHub

Maybe someone can explain it? Looks like bug.

The account that’s shown for a commit depends on the author email recorded in the commit itself. Most likely the email address in that commit is still connected to your old account.
