Some villager spawn as default brown coats with no trades

Some of the villagers that spawned had a regular brown coat texture. They also would not open the trade menu.

What I expected to happen was...:
They should have their new textures

What actually happened was...:
Some of the villagers that spawned had a regular brown coat texture.

Steps to Reproduce:
1. Villagers spawn or you spawn them
2. They have a default texture of a brown coat
