Problem:
After syncing strings in WPML, most translations are not visible on the website, although they are still translated in WPML. This issue is not related to cache problems.
Solution:
We recommend enabling WP DEBUG to check for any current errors that might be affecting the visibility of translations. You can enable WP DEBUG by following the instructions here: https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/
Look for errors such as "Notice: Function _load_textdomain_just_in_time was called incorrectly." If you find such errors, please provide us with the details.
If you are unsure how to use WP DEBUG, please let us know, and we will assist you further.

Please note that this solution might be outdated or not applicable to your specific case. We highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, we encourage you to open a new support ticket for personalized assistance at WPML support forum.
