Metahuman Characters asset creator, Makeup Concealer wont change color

I’ve noticed I’ve never been able to use the Concealer tool when building a metahuman. The Makeup tab allows for Foundation, but when I use it, there’s no adjustment I can make to stop the Concealer slider turning the undereyes bright orange???

I can turn it down, but it doesnt match the foundation at all. It’s like this for any new metahuman I make in 5.6, how can I fix this?
