Zombies try to bust through walls to get to villagers

While in a village, there were a few buildings whose doors were above the ground. Instead of being able to tell there was no path to the villagers inside at night, some zombies tried to break through the wall to get to them. Here is the seed and location of the village to test it out:

Seed: -596080138
Location: -427, -363

Make sure it is night to get the zombies to spawn.
