Hi there,
I checked your site and we could see that there is a problem with the layered navigation of WooCommerce which is the filtering system our plugin is based on:
https://devinera.com/grindinio-sildymo-kilimeliai/?filter_galingumas=100-w-m2&query_type_galingumas=or
In this other URL is only using this filtering system of WooCommerce which gives the same wrong result and for that reason our plugin is also displaying these wrong results.
You should deactivate plugin or change the theme until this link gives the correct results, and contact their support devs to help you make their plugin or theme compatible with this system of WooCommerce. Then if you still have any problem just with our plugin, please let us know.
Additionally, I found that your theme doesn’t offer the standard product archive page, which may give some problem while filtering. This is not something that is affecting your current problem, but this code in the functions.php of your theme, should help optimize our plugin.
if( ! function_exists( 'yith_wcan_content_selector' ) ){
function yith_wcan_content_selector( $selector ){
$selector = '.wc-columns-archive:has(.yith-wcan-filters)';
return $selector;
}
add_filter( 'yith_wcan_content_selector', 'yith_wcan_content_selector',99 );
}
Have a great day.
