They are still working on a fix. For now, there's another way to do it. Go to SELLER HUB, then click on the ORDERS tab. Select AWAITING SHIPMENT (or PAID AND SHIPPED if you've already purchased a label), then when you get to the item, pull down the little blue arrow and select PRINT PACKING SLIP AND MORE. That last step is important, you have to use the little blue arrow, otherwise it won't work. From there you should be able to print the packing slip with no problems.
