Trying to edit order detail page in Woocommerce - mysql

Question

I am working on a restaurant website using Woocommerce. Trying to display the linked products in a modal. So I have parent products and linked products(child). When user clicks on cart icon for the parent products, then the linkd/child products appear in a modal. User can then select multiple products from there and add to cart. It works almost perfectly. But I want to display the child products under respective parent product in order detail page(in admin) and in email(invoice). Currently the child products appear twice. As parent products and again under the parent. As you see the green marked products are child. I do not want them to appear again as marked in red.
