Background of the issue:
I am trying to remove the 'This Site is Registered on wpml.org as a Development Site' notice for translated sites. I attempted to unregister WPML and register it with a new site key, and I also cleared the server and WPML cache. The issue can be seen on the page: скрытая ссылка.

Symptoms:
The 'Development Site Notice' still appears at the bottom of the page for the sites скрытая ссылка, скрытая ссылка, and скрытая ссылка, even after registering WPML with a new key.

Questions:
How can I remove the 'Development Site Notice' from translated sites?
Why does the notice still appear after registering WPML with a new key?
