Issue with Fresh Animations x bare bones.

I've been noticing for certain mobs, one side of the eye is fine, but the other side is like this white. This happens when I'm using the "Fresh Animations x bare bones" over FA and BA in the modrinth launcher.

While it's a small issue, every time I notice it, it kind of bothers me. Hence the post.

I tried fixing it on my own, but nothing seems to work, if I turn it off the eyes completely work but the texture pack for the mobs does not match BA.

I was wondering if I'm doing anything wrong on my part, or if others are having this issue too. That way I know it'll probably fixed in the future, or if I can fix it on my own.

Thank you, sorry for the trouble.
