Zombie Villager robe cube is inconsistant with the Villager's

i see that you're using a texture pack, put it off and see if the problem remains

Resource packs can't change entity models, this exists regardless of resource pack.

@unknown

My friend, entity models can't be changed, only item and block models.

@B4dAtMC The resourcepack in picture 2&3 (which has the exact same mapping as vanilla zombie villagers) is not the cause as this occurs even in its absence (reference picture #1). Resourcepacks cannot edit entity models. Please do not lecture others about things you don't understand.

sorry @unknown D:

I’m having difficulty knowing if I am reproducing this issue correctly. Please can you provide a good way to reproduce the issue?

It was temporarily resolved as "Awaiting Response" in regards to GreyMagic's question, which is yet to be answered.
I've re-resolved the report as AR, please do not open it again (by commenting) unless you have new helpful information to add.
