[נפתר] switching language does not work correctly

Background of the issue:
I am trying to change the menu from the Dutch menu to the English menu on my site קישור נסתר by using the flag above. It is important that visitors can click on the flag. I have placed a temporary option next to the flags 'English - Click here' to navigate to the English homepage.

Symptoms:
Switching language does not work correctly when using the flag to change from the Dutch menu to the English menu.

Questions:
How can I ensure the language switcher flag works correctly to change menus?
Are there specific settings in WPML that I might have missed to enable proper language switching?
