Debut Theme - Main Menu Dropdown not working

Hello!
I tried to add a new menu item to my live site : https://librairiewinobooks.com/. The new menu item is the one called “Affiches” and I added a sub-menu item called “De Long”. However the dropdown is not appearing on the live site as it does for my other menu items like “livres”, “magazines”, or “zalto”.

Update: Testing further, no edits to the main menu appear on the live site. But they do appear on the customize in admin.

Hi @WINO ,
In the attached file, first item of the menu is “LIVRES” while on your store first item is “BOOKS” .
Are you sure you have linked this menu (attached image) to the header in your customizer section?

Hi, that is good

Hi @WINO ,

I checked your site and I see it worked. please confirm and give me feedback. if you have any issues then let me know. thanks

Hope my solution works perfectly for you!

Best regards,
