Breacrumbs leading back to Home page only

[Sigurd]

On the village web site, the section on War Dead, the breadcrumbs do not properly. If you look at the stbees.org.uk web site and select Village History, scroll down to Memorials and select World War 2, the breadcrumb trail is correct. (Sorry - not allowed to post Links yet!). However, if you select Bell, Coward, or Rodgers, the breadcrumb is partly correct, though it goes back to a different access page. Selecting any other name is totally wrong as it goes right back to the Home page.
I am using Elementor Pro, for editing and Yoast SEO for the breadcrumbs. The Theme is Astra Pro.
Needless to say I am barely out of the Newby category!
