On the Batch Listing Page, you may see, as pictured here, that "Force Case-Packed" is grayed out and you can't disable it. 


There is a setting that, when enabled, renders this setting "sticky," and it can't be disabled. To change this, click the settings button (red arrow), then you have the option of turning off the "Multipack calculates shipment quantity," setting (in red). You also have the option of turning off the Multipack Size column, then (in green). Then click "settings" to save. If the "multipack calculates shipment quantity" is selected, you cannot turn off the "force case packed" setting. It will be grayed out.  But after disabling the "Multipack Calculates Shipment Quantity," you will be able to disable, "Force Case-Packed."
