This thread is resolved. Here is a description of the problem and solution.
Problem:
The client needs to translate page slugs in multiple languages except for Chinese, where they want to keep the original slug untranslated. They were unable to find an option to exclude only one language from slug translations and had issues reverting already translated slugs.
Solution:
We advised the client to navigate to WPML > Settings > Translated documents options. Under Page URL, they should select the Translate option and save the changes. This setting allows the slug to appear in the translation editor, where the client can choose to either copy the original slug manually or translate it for each language. For existing pages, after applying this setting, the client should update the page or post in the default language and then access the translation editor to see the option to translate the slug.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking the related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If issues persist, please open a new support ticket.
