Hi – I’ve been using the basic version for 6 months. Recently, maybe upon the new update a bunch of Woo Commerce Code is printing on the invoice as the product description. Specifically the products in the bundle – are printing more code than they used to. I am using WooCommerce Product Bundles: WooCommerce extension for creating simple product bundles, kits and assemblies.
