Breadcrumbs: not showing WPML translation only for ACF Main Custom Taxonomy

Hello Team Yoast,

I hope you are well. I need your help with the breadcrumbs. I used custom taxonomy created with ACF and translated with WPML.

The issue is that the breadcrumbs do not take the translation of the main custom taxonomy but do translate well the sub-taxonomies. I need the main taxonomy to be translated too.

To give an example: if the main custom taxonomy is called ‘main taxonomy’ (translated in french with ‘taxonomie principal’) and the sub-taxonomy is ‘sub-taxonomy’ (and in french ‘sous-taxonomie’), below is how the breadcrumbs should be shown in FR on the sub-taxonomy archive page :
Accueil > taxonomie principal > sous-taxonomie

But instead, it is displayed like this in french:
Accueil > main taxonomy > sous-taxonomie

Could you please help me out on how I should set up Yoast with ACF and WPML so breadcrumbs are well-translated including main taxonomy translation?

Thanks a lot for your help,
Kind regards,
Sophie
