How to hide net value of $0 on Credit Memos from rejected return?

We are creating a credit memo request with a second line item which contains rejected returns. Basically line item 1 contains the actual qty which we are refunding and line item 2 is the qty which we will not be refunding. When we create the the credit memo from this document in VF04, the line item two is showing on the credit memo with a net value of $0.

Is there a way to hide this net value of $0 or rejected return items from coming over onto the credit memo. We would like to just show positive values on the CM.
