Piglins and zombified piglins look weird

Piglins have no left ear, and the texture of both their right ear and the sides of their tusks is wrong. Similar case for zombified piglins, but of course it's their left ear instead, and the part of their texture that the ear and tusks are wrongly using appear to be in different spots of their texture compared to the piglin. Weirdly, it seems like when 2 piglins are on-screen, one of them gets their right ear changed to the right texture, but their tusks disappear. (I wasn't able to get a screenshot of this) I don't know if a similar thing happens with zombified piglins, what happens when more than 2 piglins are on-screen, or if the texture of piglin brutes is also broken as well.
