I created a bundle named "Tanship" and included three products in it. As we can't provide a product with $0, I created a coupon only for the "Free" product.

Problem: When you open the "pro" link, there is no "apply discount" field, which is not a problem. But when we click on the "free" option from there, then "apply discount" does not show. So it's an issue. Although once you refresh the page, it becomes available for a discount. It's a problem.
