[Fermé] Product appears in wrong country

Background of the issue:
I am trying to manage product visibility on my site lien caché using WPML. When I switch the language for a product in the US, it shows the US version of the product with the language URL, even if the product does not exist in that language. This issue is specific to switching from the US to other countries.

Symptoms:
When changing the language for a product in the US, the US version of the product appears with the language URL, even if the product is not translated to that language. This issue does not occur when switching from other countries to a different language; instead, it redirects to the homepage.

Questions:
Why does the US version of the product appear with the language URL when the product is not translated to that language?
How can I prevent untranslated products from appearing in other languages?
Why does the issue only occur when switching from the US to other countries?...
