Variation issue – showing all variation permutations

Hi there,

I have a product with over 700 variations, created with 3 attributes. The problem is that the filter process doesn’t work e.g. if I select attributes 1, it still shows all possible attribute options for 2 and 3, and doesn’t limited choices based on attribute 1.

However it displays a message at the bottom like this to say that the choice I made is not avaiable:

I changed the theshold using this code:

function woo_custom_ajax_variation_threshold( $qty, $product ) {
return 1500;
}
add_filter( ‘woocommerce_ajax_variation_threshold’, ‘woo_custom_ajax_variation_threshold’, 10, 2 );
function wpse_rest_batch_items_limit( $limit ) {
$limit = 5000;

return $limit;
}
//add_filter( ‘woocommerce_rest_batch_items_limit’, ‘wpse_rest_batch_items_limit’ );

But it didn’t seem to help.

Any help here would be really appreciated…
