static homepage created but not showing in Reading Settings drop down

A WP newbie, I’m having problems setting up our first pages.
A homepage and blog page have been created, though published as private not public.

However, when I try to set the static front page and the blog page in Reading Settings, the drop down for selecting a page only shows Sample Page, and similarly when I try to set the home page and blog page using Customize > Customize Homepage.

Please would you advise how to sort this?
Thanking you in advance for your help and advice.
