Plugin not loaded with too many variations

Hi. I have a problem with your Variation Swatches for Woocommerce plugin. Sometimes the javascript library that manage the frontedn is not correctly loaded by the browser and thus all option – even those not available – are shown as available. Some months ago I contacted you for the same reason and your assistance team gave me a snippet for my functions.php file:

// Increase Ajax threshold for Woocommerce Variations Switches plugin (otherwise it won’t work for variable products with a large amount of variations)
add_filter( ‘woo_variation_swatches_global_ajax_variation_threshold_max’, ‘woo_variation_swatches_global_ajax_variation_threshold_max_edit’, 10, 2 );
function woo_variation_swatches_global_ajax_variation_threshold_max_edit( $size, $product ){
return 700;
}
add_filter( ‘woocommerce_ajax_variation_threshold’, function($qty, $product){
return 100;
}, 10, 2 );

This has not helped me: the problem continue to occur. Any idea?
