    Description of $page parameter may be misleading. It can be interpreted as if needs to be the slug name of the admin page created through add_submenu_page() or one of its wrappers (such as add_theme_page() or add_plugins_page()). Instead, it only needs to be a slug-formatted name used by add_settings_field() and do_settings_sections().
