Inaccurate Zinc Content for Canned Oysters

Hi,
As a Gold member, I'm generally satisfied with the app. However, some inaccuracies in the database are raising concerns.

For instance, when searching for 'Bumble Bee Canned Hardwood Smoked Oysters,' the app shows zero zinc content. Yet, searching for 'Crown Prince Natural Smoked Oysters' reveals a significant amount of zinc. This inconsistency is puzzling, especially since most other canned oysters also display zero zinc, while "Oracle Nutrient Search" confirm oysters as a top zinc source.

Could someone explain this to me?

Thanks,
