This thread is resolved. Here is a description of the problem and solution.

Problem:
The client was experiencing an issue where the 'Load More' button on their AJAX-powered page was not loading the fallback language posts when switching to French, despite having the fallback option enabled.

Solution:
We recommended checking if the language cookie support for AJAX was enabled by following this documentation: https://wpml.org/documentation/getting-started-guide/language-setup/enabling-language-cookie-to-support-ajax-filtering/.
Additionally, we suggested that the client should try duplicating at least one post into the translated category to see if it makes a difference. If the issue persists, we advised the client to follow the instructions provided in a forum topic that addresses a similar problem with wp_query not falling back to the default language: https://wpml.org/forums/topic/wp-query-does-not-fallback-to-the-default-language/page/2/#post-15098171.

Please note that the solution provided might be outdated or not applicable to your case. If the issue persists, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.

hidden link

Let me know once you have it all in place or if you have questions related to sandbox.

I just implemented the same code on the sandbox installation.
So I created on EN a page hidden link and a shortcode in functions.php listing the first 3 posts, with a load more button.

There are 4 whitepaper posts in total, in English, assigned to the category Whitepapers (ID 13).
The category is translated into FR - hidden link with ID 14 (but empty as no french whitepaper posts exist yet)

So just like on my installation, on the EN page hidden link it all works fine - the 4th post gets loaded (after the query args for debugging reasons).

Instead on the FR page hidden link it doesn't.
Again, that [category_name] => livre-blanc arg gets used for the query and therefore I suspect it creates the issue, as that category is indeed empty. It should fallback on the english Whitepaper category.

Let me know if I'm doing something wrong.
Thanks a lot!
