Home page not displaying posts when re-selecting

Hi

I’ve been helping to set up a blog for a project by a not-for-profit genealogy organisation.

The Home page has a sticky post at the top then will display all the blog posts under it. When you go to the site, all looks well.

However, if you navigate away from the Home page to another using the Menu, then click back on Home, it no longer displays any of the posts, only statistics of views.

I have no idea what is causing this or how to fix it. Does anyone have any ideas?

Many thanks

Melody
