I don't think this is a display issue. I believe the service doesn't have features in the area. I tried displaying this layer in ArcMap, with the same results. ArcGIS.com sends the queries to the service, but the service doesn't return any features.
There may have been some error when creating the service that the features didn't get loaded properly. Interestingly, you must have deleted or unshared the service, as I can't access it anymore.
THanks,
Mike
