[Закрытые] The menu popup doesn't work as it should when the language is switched to French and Italian

Background of the issue:
I am trying to ensure that the mobile popup menu works correctly on tablet and mobile views when switching languages to French and Italian. The default language, German, works fine. The issue can be seen on this page: скрытая ссылка. I have checked translations, popup templates, and tested on my local installation. I also deactivated all plugins except Elementor and WPML, but the issue persists. The theme in use is Hello Elementor.

Symptoms:
The menu popup doesn't work properly in French and Italian. Submenu items lack necessary attributes, and the popup cannot be closed using the X icon. There is a JavaScript error in the console: 'Uncaught ReferenceError: showThisFieldIf is not defined'.

Questions:
Why does the popup menu not work correctly in French and Italian?
What causes the JavaScript error 'Uncaught ReferenceError: showThisFieldIf is not defined'?
