Bug in the appearance of the villager and zombie villager with the classic texture

If you put the classic texture, the villagers and zombie villagers will have the wrong texture

What I expected to happen was...:
When the standard texture was changed by the classic texture, the villagers and zombie villagers were left with the default texture or the old texture

What actually happened was...:
Villagers from all biomes and all professions are left with a green hood and zombie villagers from all biomes and all professions are left unarmed and with something like an areola on their heads

Steps to Reproduce:
1. Spawn a villager and a zombie villager
2. Change the default texture for the classic texture
