Second nav is merged with the first in mobile

In functions.php, change the function magazine_responsive_menu_settings() to the following:

function magazine_responsive_menu_settings() {

    $settings = [
        'mainMenu'    => __( 'Menu', 'magazine-pro' ),
        'subMenu'     => __( 'Submenu', 'magazine-pro' ),
        'menuClasses' => [
            'combine' => [
                '.nav-primary',
                '.nav-header',
            ],
        ],
    ];

    return $settings;

}

Basically, in the combine, I removed '.nav-secondary',

This is how it looks like now
