Villagers' arm textures are incorrect in the Halloween Mash-up pack

Steps to reproduce:

1. Ensure you own the Halloween Mash-up pack
2. Create a new world with the Halloween Mash-up resource pack enabled
3. Spawn a few villagers

Observed result:
The villagers' arms have a skull-like texture.

Expected result:
The villagers' arms are properly textured, like in the mash-up pack world template and like in Legacy Console Edition.

Original description:
I post two images showing a villager from minecraft console edition with normal textures on his hands, while in bedrock I post an image showing that he has bad textures on his hands. All this happens in the halloween mash up pack.
