[2021] Codex statistics are wrong

Hi all, I'm trying to unlock the engineer Lei Cheung, who needs one to have traded at 50 unique markets. I certainly have more than 0 markets traded at, because I got to elite in trading by doing single hop trading routes and had to change where I was going to and coming from many times. Yet, my codex says that my "market network" is 0. My trading profit is 0 and so is every other statistic on this page. This can't be possible as I understand it, because I have around two billion in trading profits and I've spent a good deal of time going to many different stations to trade commodities.

Is there only a particular kind of trade that qualifies? Or is this a bug?
