Order number I was working on was 9583515 but I've had this issue in the past and didn't report it. I usually zero it out and use the refund adjustment field.
Maybe the error message can be improved to say that "You can only provide a refund for shipping costs received. Order shipping was $0.00 and refund must be less."
