Thanks for your patient. We had a deep look into your site and we have found that your theme is missing a WooCommerce hook which is
do_action( 'woocommerce_product_thumbnails' );
If you want with your permission we can edit your site’s child theme and place it there for you or you can do it yourself.
Also, please have a look at this page: https://boomdevs.com/docs/woocommerce-product-badge-manager/advance-badge-integration/using-shortcode-to-show-badge/
We already have a solution to this problem in our documentation.
We won’t take any action until we hear back from you.
