Maybe it's her age. I mean I really get confused too at first not untill you said "age" and gender. So it is most likely with gender but I want to know toooo.

Maybe she lied in chat. Like her avatar is a girl but she said she’s a guy and fake her age too.
It says Hyejin got kicked out if the clan for faking her age and gender, but her avatar was clearly a girl, so shouldn't she be a guy? But she knows Seyeong's a guy, so she has no reason to hide it, so she's actually a girl and her avatar just makes no sense?
