WPML language switcher still not working

Hello,

I’ve installed WPML and Enfold sets a default language switcher. I’d like to change that to a dropdown menu. I know that there are threads about this topic, the provided codes in these threads don’t do anything:

Ismael provides a code here: https://kriesi.at/support/topic/language-switcher-3/

If I add

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 );
        remove_filter( 'avf_fallback_menu_items', 'avia_append_lang_flags', 20, 2 );
        remove_action( 'avia_meta_header', 'avia_wpml_language_switch', 10);
}
add_action('ava_main_header', 'ava_icl_language_selector');
function ava_icl_language_selector(){
	do_action('icl_language_selector');
}

the language switcher by WPML is added, but the Enfold switcher remains also.
Here is a screenshot: https://one-bound-beyond.org/screenshot/
How can I remove the Enfold switchers?

Best regards,
Niklas
