Is it just me or aren't the food items showing up in Unnie Deal?

In the past, searching for things like sweet potatoes, tomatoes, and carrots would bring up results, but now they don't show up at all... When I searched for sweet potatoes, items from various sellers used to appear, but now only frozen sweet potatoes and sweet potato shakes show up... However, it doesn't mean the items have been deleted, because if I go into my purchase history, I can still buy the sweet potato products I purchased before...

Why aren't food items showing up?? They've completely disappeared from the sales rankings.
