Woocommerce terms & conditions duplicated in checkut page

Hi I read a little bit in the forum about the issue of Terms&Conditions duplicated in the checkout page but I didn’t find any viable solutions, or at least in my case it didn’t work.

In this post it is suggested this filter

add_filter('woocommerce_format_content', 'yanco_remove_inline_terms', 10, 2);
function yanco_remove_inline_terms( $apply_filters, $raw_string ) {
	if( is_checkout() ) {
		return '';
	}
	return $apply_filters;
}

However if I use it the terms&conditions page doesn’t appear anymore

Moreover, since my T&C page as a special header and an accordion, I realised that the part of it contained in av_section_1 (containing the WC checkout elements) the accordion doesn’t work (it doesn’t open), while the duplicated accordion in the below section (av_section_2) works nicely.

Could you please help me in solving this problem?
I can hide the av_section_2 (suggested in this post), but I’ll keep the accordion that actually doesn’t work.

Otherwise I can use the filter mentioned above, but no T&C would be visible

Thanks for help
