[Закрытые] WooCommerce Email Notification Language Change Not Working properly with Object Cache

Background of the issue:
I am trying to change the language of WooCommerce email notifications via WooCommerce > Settings > Emails. I attempted to switch the language flag from Greek to English in the email settings.

Symptoms:
When I press save language, it returns to the original one. This issue does not occur if I clear the object cache or disable Redis.

Questions:
After investigation I concluded this is an incompatibility of WPML with object cache. If I clear object cache or disable Redis totally, this issue is not replicating. Maybe WPML devs needs to look further why changing the flag and saving emails settings are not clearing object cache automatically.
