How to remove the WPML language flags from the menu?

Hi, I already asked this and got a reply that said to add this code:

add_action('after_setup_theme','avia_remove_main_menu_flags');
function avia_remove_main_menu_flags(){
        remove_filter( 'wp_nav_menu_items', 'avia_append_lang_flags', 20, 2 );
}

Which I did and it worked great as you can see here – http://polytowncoil.staging.wpengine.com/ (hosted on WPengine)

BUT, I just noticed that after upgrading to Enfold 3.0 the flags are showing again as you can see here – http://polytowncoil.staging.wpengine.com/blog/ – http://screencast.com/t/5dyEAOQKn

I’m using a plugin that allows me to create custom menus for each page on the site. The plugin is called Zenu Menu logic just so you know if that has anything to do with it (although I don’t think it does).
