This page not allowed page comment, and doesn't allow page wrapper option. This page template made for Elementor page builder only so if comment detected from post, your page comment doesn't come up. Also doesn't have Page Title.
Other page template will shown after you installed the required plugins, such as "Elementor Canvas" and "Slider Revolution Blank Template". Both of these pages are not stylized by us and will disappear after deactivate active plugin.
