my henchmen looks have always worked as well.
They don't have any issues when you load a save? Other people have had the same issue even with default henchmen, I don't think it's specific to custom ones.
I tried using a new GUID and while it fixes the list, it definitely doesn't fix appearance. I really wish we could nail down what is causing that issue, because it's worse than the list bugging out in my opinion. Kind of sucks not having them stay the way you want them to look (unless you port every time you load a save).
