How to have uploaded files show in order details

Hi,

I have installed this plugin and added a file upload field after the billing form. It works but when I view the order details in Woocommerce Orders, The order uploaded file is not shown under the “Order Uploaded Files” section. The file is in the media library though.

How can I make it so the uploaded file will appear in the order detail page’s “Order Uploaded Files” section?

Thanks!
