Pb of template ?

Hello everyone,

I got a little problem on a website I haven’t built but I have to admin.
It uses WP 6.1.3, a child theme from Avada 5.8.2 and CPT 1.13.1.

This is about a page which uses CPT UI to display 2 lists of books. When clicking on a book, we se the “detail page”.

Here is the right behavior on my <span style=”text-decoration: underline;”>dev</span> version :
– List : https://dev.prixlitteraire.lestock.net/la-selection/
– Detail : https://dev.prixlitteraire.lestock.net/la-selection/bel-abime/

In the <span style=”text-decoration: underline;”>prod</span> version, the behavior seems ok but the breadcrumb is wrong :
– List : https://prixlitteraire.lestock.net/la-selection/
– Detail : https://prixlitteraire-regionsud.fr/la-selection/les-enfants-endormis/
– But the breadcrumb : Accueil>Archives/2023/2024/Les Enfants?endormis
(And I’ve hidden a sidebar which is not when the list).

In the prod version, it looks like WP chooses another template when displaying the “detail” page. But i don’t find where can be this parameter.

Thanks to someone who could help.
