I’m having trouble placing a page with a custom design. The page template option does not appear in my WordPress. Version 5.2.2The model I created should appear. page-blog.php
The Page Template menu will only show if there are page templates. The page template has to have the correct PHP comment at the top so that WP knows it is a page template.

According to the Template Hierarchy, a template named page-blog.php would be selected automatically for a Page with a slug of blog
, so it is recommended that you name your page templates so that they don’t start with page-
.
