CC Default Skin not Working Properly

So, I've been using madmono's knight skin for awhile, and it shows up in CAS always, but sometimes in live mode it doesn't look like it's showing up. And it's not on every single sim, just some of them. I'll post comparison pictures of my sim Parker for reference, because it used to show up on him and now it doesn't. All of my mods are up to date as far as I know. Could it be other CC making it do that? If so, what's an easy way to find what's causing the issue?
Here's Parker in live mode before the issue started happening

Parker in CAS. The skin is still fine here.

And here's Parker in live mode now. It probably looks like a really subtle difference but I can tell that something is off.
