App is not really helpful for me

I entered 3 bar codes and got a "No data available. Enter another bar code" msg. (note: exact wording may have been different, but the message was clear.) My problem is the 3 wines I entered are NOT esoteric or rare wines: Beringer Knights Valley cabernet, Oyster Bay sauvignon blanc, and. You get the point. These were test bottles from my "table wine" rack. Perhaps the particlar vintages are no longer in shops (test bottles were purchased 6 months ago.) whatever, I expected one of these would have been reviewed. Oh well. Thankfully the app is free. So no real loss, just a bit of a disappointment.
