We have the same problem. It worked perfect with Woocommerce Bundle. But after Upate to the newest WooCommerce Version, the Items of the Bundel are not displayed in the order. Only the Bundle. Example: Buy a Bundel “Cap and Shoes”. Select the Size and Color. But after Update: In the order is only the Bundel, not the Size and Color. How can we fix it? Shop is still only.
