Cannot find page in Admin to edit it

I have a page that I can only find by searching my website pages that is at the domain level. I cannot find this page to edit or remove in my Admin section. It is not inside of any of these collections or cover pages, either.

Page: https://danellebailey.com/bivariate-choropleth-map/ 


Note: I found a similar post, but the answer was not helpful. (https://forum.squarespace.com/topic/175465-a-page-is-live-on-my-site-but-cant-find-it-in-my-admin-menu/)

First, access this url: https://danellebailey.squarespace.com/config/

Next, access this url: https://danellebailey.squarespace.com/bivariate-choropleth-map/

Thank you so much! I can now edit the contents of this page! 

Now, how would I delete this page? It is not displaying in the sidebar anywhere.

You will manually check each page in turn. When you are editing a page, it will be highlighted and have a different background color than the other pages.

For example, I'm editing "Scroll block test" page, you will see its background is different

You may need to check your hidden or archived pages in the admin section.
