Villagers won't take food when you throw it at their feet.

After the update I went into my village, zombies nearly killed off my village, so I wanted them to have kids, I threw potatoes at their feet and they didn't take it, I blocked two in a house and threw various foods on the ground; beets, wheat, bread, potatoes, and carrots. They ignore it and walk through it. Farming villagers can give food to other villagers and they accept it.
