[Résolu] button in menu to a page goed to the main language

Background of the issue:
I have a button in the menu on my website, lien caché, which is supposed to link to an agenda of events. I am trying to ensure that this button works correctly on translated pages.

Symptoms:
When I click the button from a translated page, it redirects to the main language (Dutch) agenda page instead of the translated version.

Questions:
How can I make the button link to the correct translated agenda page?
Is there a setting in WPML that needs to be adjusted to fix this issue?
