Wasn't anything I could do to help in the list of saved passwords, or logging out from the account. Even deleting the account didn't seem to do the trick. Then I cleared/wiped my entire browser history, and after that, I got a blank log in for google instead, and was able to set up the correct account.
Thanks, though, because your suggestion made me play around with it more, until the problem was finally solved.
