You must open the Image Tab in each newly added Change Order one-at-a-time, click the DPC Button, then return to the Bids Tab and select any other Change Order added after the original Bid Package was sent to the field and repeat this process before setting the Base Bid back to DPC Mode. DPC only requests updates from Quick Bid for a Change Order when the DPC Button is clicked within that Change Order.
Do not use the Bid View drop-down to switch between Change Orders or the Base Bid, return to the Bids Tab.
