        Form::setError("validation", __("Error: Confirm password does not match with new password"));
        $error = true;
    }
    $entered_pass = generateHash($_POST['oldpass'], $loggedInUser->hash_pw);
    if ($entered_pass != $loggedInUser->hash_pw) {
        Form::setError("validation", __("Error: Wrong old password"));
        $error = true;
    }
    if ($error == false) {
        Form::clearValues("validation");
        $stmt = $mysqli->prepare("UPDATE " . $db_table_prefix . "users
        SET
        email = ?,
        password = ?
        WHERE
        id = ?");
        $newpass = generateHash($_POST['password']);
        $stmt->bind_param("ssi", $_POST['email'], $newpass, $id);
        $result = $stmt->execute();
        $stmt->close();
        $successes[] = __("Updated settings");
    }

}

Whenever I load the form, the errors always appear, any idea why?

Yep.. was mostly stupidity on my end

if (!empty($_POST)) {
  //PFBC Code goes here
}
