[Resolved] Problem with synchronization of some menu items

Problem:
The client is experiencing issues with the synchronization of some menu items when switching languages on their website. Despite following the WPML documentation for translating menus, certain items like 'Home > Úvod' and 'About us > O nás' are not working correctly.
Solution:
1. Ensure you have a full backup of your site.
2. Navigate to WPML → WP Menu Sync and click the Sync button to review and apply suggested changes.
3. For unresolved items or custom links, use WPML → String Translation to add necessary translations.
4. Revisit WPML → WP Menu Sync and perform the sync again.
5. Manually adjust the menu in Appearance → Menus, ensuring each language's menu matches the intended structure and save the changes.
6. If issues persist, disable any redirections that might be hiding certain language versions of the site, as found in the site's redirection settings.
7. Address any visible errors in the WPML support page.

If these steps do not resolve the issue, it may be due to specific configurations or conflicts on your site. We recommend visiting our known issues page to check for similar problems and solutions.
