I have 3 scenarios and I'm hoping to take care of them with the same template. There is a GS1-128 barcode present with 3 AI elements (GTIN, LOT, EXP). 

• Scenario 1: All 3 elements present on the item. This is working great.
• Scenario 2: The item has a GTIN, LOT, but not necessarily an expiration. The label prints, and the barcode prints, but the unnecessary AI prints with nothing after it. Can this AI (17) be left totally off the barcode in this scenario?
• Scenario 3: The item does not need this GS1-128 barcode (for UDI purposes and should be left off or not visible). No data is sent for any of the AI fields. Right now Bartender is giving warnings and printing no label.
