Partial refund not shown on Packing Slip

Dear support,

When creating a packing slip for an order with a partial refund, the refund is not taken into consideration.

Consider this scenario:

1. Customer place an order
2. A partial refund is created
3. The Packing Slip is printed
4. The order will be prepared including the refunded item!

I found a previous topic related to invoices, but this is about packing slips that has affects the operations.

Do you have a solution for this?
Is this a bug?

Thanks
Daniele
