[Fermé] Taxonomy Terms Not Duplicating Across Languages

Background of the issue:
I am developing a multilingual site using WPML with German as the default language and French as the secondary language. I am trying to ensure that taxonomy terms created in German are automatically duplicated in French.

Symptoms:
When I create a new taxonomy term under 'dealstore' or 'coupon store', it is created correctly in German but not automatically duplicated in French.

Questions:
What might be causing taxonomy terms not to duplicate across languages?
How can I ensure taxonomy terms are properly duplicated across languages?
