Some prices doen't disappear when switched to catalg mode

i need chage my page to catalg mode, but in some page like a widget where i display the best product, the prices don’t hide, same at the begin of my page, where i have a option call single product. How can fix it?, because i add this to my functions.php and doesn’t work too:
add_filter( ‘woocommerce_get_price_html’, ‘myprefix_hide_all_wc_prices’ );
function myprefix_hide_all_wc_prices( $price ) {
return ”;
}
my page is bordadoselencanto.com
