Shipping Address on Address box on the Item Fulfillment is different from the Shipping Address Fields

 

This is possible if you check the Override checkbox in the item fulfillment.  

When fulfilling an order the shipping address is automatically pulled up in the Shipping Tab of the item fulfillment. Normally, the values entered on the Addressee, Address 1, Address 2, Attention, City, State/Province, Zip and Country is being displayed in the Address box. Once you mark the Override checkbox next to the Address box, you can change the values directly from the Address box but the values in the Address Fields will not change. No changes (blank)  will also be logged in the system notes.
