Hyvee still charging food tax

Just purchased a few things at Hyvee today. Went back and looked at the receipt, some of the items are still charging sales tax post Governor Kelly's grocery sales tax cut. I understand some items are not considered grocery, but that is not what's going on. Bought a couple frozen pizzas and juices. Some of the pizzas, no tax, the other pizza was charged tax. Same story for same brand for 2 juices. 1 taxed, 1 not..
