Thanks so much for the response, but unfortunately, it hasn’t helped.
When I get to the list of templates, I do not see any of the pages I created. I do however see the page template types and I selected “blank” as that is the type of page that I added. There are no options. It is a blank, white page with the following text “This is the post content block, it will display all the blocks in any single post or page. That might be a simple arrangement like consecutive paragraphs in a blog post, or a more elaborate composition that includes image galleries, videos, tables, columns, and any other block types. If there are any custom post types registered at your site, the post content block can display the contents of those entries as well.”
