The infamous quantity field disappeared a couple of months ago. We provided another method to add additional shipments after creating the first, but that required a couple more clicks. We were working on a bigger redesign of this functionality, however we noticed that this functionality was dearly missed so we added it back for your convenience.

Please keep in mind that quantity does not create 1 shipment with X amount of packages, but creates X amount of duplicate shipments with 1 package. We are working hard on making the first option possible.
