The page shows Grab&Go orders (the Grab&Go checkout type) for the selected retail location whose delivery date falls between Begin and End. Both dates must be existing delivery dates; if either is not a delivery date in your calendar the list stays empty, so widen the range or pick real fulfilment dates. Orders for wholesale locations are not listed here - those are handled by the wholesaler in their portal - and orders placed for a different location appear only when that location is selected in Select Retail Locations.
