[Résolu] WPML and chance language

Background of the issue:
I am trying to fix a problem with the language switcher on my website. When I change the main page's language to English, it redirects to the news page instead of the expected English version of the main page. The issue can be seen at lien caché.

Symptoms:
When I change the language to English, the site redirects from lien caché to lien caché instead of lien caché.

Questions:
Why does the language switcher redirect to the news page instead of the English main page?
How can I configure the language switcher to redirect correctly?
