Potatoes and bread everywhere in villages

When it's daytime and I walk in villages, I see stacks upon stacks of potatoes and bread randomly pop up everywhere. It has been two Minecraft days and I have filled up over 2 large chests full of potatoes, and gotten around 5 stacks of bread. And the next day, as you can see in the screenshots, enough stacks of potatoes to fill up at least 3 large chests spawn in groups! I want this fixed, weird glitch.

EDIT:
I then decided to destroy all the farm dirt of the gardens in the village, and the glitch never occured again. Also, I visited another village in the same world, and the glitch occured with carrots this time... makes a great way to get easy emeralds though
