Metahuman necks are distorted by default

I noticed that all metahuman necks are (very slightly) distorted by default. When i check on “disable post process blueprint” the neck obviously goes back to normal and prevents animations from working, the necks are distorted with or without animation data, it’s like the default rest position of the skeleton is somehow bad by default, and i just want to know if somebody can share a link to show me how i can fix the default rest position of the entire neck, because i really think that’s the issue by default with all metahumans, as far as i’ve seen.

Here’s an example of this problem, it’s very subtle it almost goes unseen.
