Home link duplicated

Hi,

I’ve used this menu on my site https://cssmenumaker.com/menu/red-css3-drop-down-menu and wanted to show the ‘Home’ link on the navigation.

I’ve implemented the code

function home_page_menu_args( $args ) {
$args['show_home'] = true;
return $args;
}
add_filter( 'wp_page_menu_args', 'home_page_menu_args' );

to call the home page, but I suspect due to cssmenumakers own css, it’s causing the Home link to duplicate.

Can anyone help me out this this? I’d really appreciate it!!

Thanks
