Background of the issue:
I am trying to use automatic translation with WPML. We found a bug with automatic translation and admin language. As soon as there are products under automatic translation, the admin language of the back office keeps changing. The default language is French, but it changes to English, then to Portuguese. We didn't have this problem before with the automatic translation disabled.
Symptoms:
The admin language of the back office keeps changing from the default language (French) to English and then to Portuguese when automatic translation is enabled.
Questions:
Why does the admin language change when automatic translation is enabled?
How can I fix the issue of the admin language changing unexpectedly?
