Can no longer hide icons on desktops and tablets

I have a website on which I was supposed to change the icons. But realized that the function on the WordPress menu that hides the different responsive sizes no longer works.

I have two menus in my title, one for the mobile version of the menu and the other for the desktop and tablet versions. I can no longer hide the mobile version on desktop and tablet. Everything else is fine, just the wordpress menu widget.

Does anyone know a solution to this problem?

Other than Elementor and Elementor Pro, I only use ACF as a plugin.
