No “Upload” Button to Attach Downloadable File to Product

I am using Jigoshop Ecommerce 2.1. I need to go through our website and re-upload and attach digital files to over 300 products, since they were deleted due to the update. There used to be an “Upload” button to add files to a product – “Product Data -> Downloads -> File Path”. Now, there isn’t. Is there a way to get the “Upload” button back? It’s very hard to locate the correct file path for each product, without that “Upload” button.

Thank you,
