Thank you for contacting WPML Support. To take a closer look at this issue, please provide temporary access (WP-Admin and FTP Login info) to your site (preferably staging site), so that I can look into your setup and debug the issue.
Your next answer will be private which means only you and I have access to it.
=== Please backup your database and website ===
✙ I would additionally need your permission to deactivate and reactivate Plugins and the Theme and to change configurations on the site. This is also a reason the backup is really important.
Thanks for providing the login details. I logged in to your site and opened the Elementor header template: hidden link in the default language and selected the Menu as you can see in the attached screenshot.
Now it seems to be working correctly. Could you please check and confirm?
