Some villagers do not lock the doors of the village houses or made by the player, they do not close the doors during the day or at night and a zombie can kill them

What I expected to happen was...:

villagers lock doors when leaving or entering a house and close them when they go to sleep

What actually happened was...:

they do not close them day or night

Steps to Reproduce:
1. 

Living in a village in survival and/or building houses for villagers

2. See if the villagers close the gates day and night
3.
