Hide unavailable variations

Hi

I really loved the simplicity of the plugin and how easy it is to style ?? i only have a problem with my variations still showing even though i have removed them from list ( non existent ).

I managed to control the ajax threshold

function custom_woocommerce_ajax_variation_threshold( $qty, $product ) {
     return 500; // Set 1000 to another number to load faster
}

add_filter( 'woocommerce_ajax_variation_threshold', 'custom_woocommerce_ajax_variation_threshold', 10, 2 );

and it greys them out, which is fine. but i’d prefer to have them not showing at all as they cause confusion while selecting.

my attributes are : Style | Color | Size
the unavailable “sizes” and “colors” were disabled as i mentioned before ( i did it by not assigning a parent id to them in the CSV file before importing to woocommerce )

Thank you
