The problem with the custom page name

[Makar]

Good afternoon.
Ustavnovil component to your website.
There was a need to do seo title for categories. I saw that it is possible, and it's called: User name of the page
But here's the problem. It does not replace the page name. She did not produce any action not.
Since php knowledge is not my forte. Podstkazhite that it should be replaced?
