How do I properly give a customer a refund for combined shipping? 3 separate listings ?

[magnetsplus]

I recently sold 3 items to a customer, who could not get the combined shipping discount, because of the separate listings. I issued the customer a $4.00 refund thru paypal, but it now shows up in my summary as unpaid. How do I remove this as an unpaid item?
