summer 2020 bingo question

Hello, I just started playing for a week or so. I've been doing pretty ok on my own thus far. I have 3 bingo slots left on my card and 2 of them I have no clue about. I have left b-3 (uninvited intruder) but that one I have waiting to complete. the other two are a-4 and c-5 both say they are client order's from XIA but I don't see them offered from her. Do I have to unlock them?

Yes, Xia has client order that unlock as you complete her previous ones.
