I heard the same thing about the lack of club/city names for some people. There was even a married couple who registered at the same time the same way, one got the info listed and one didn't. I don't know who prints those, I'm guessing the AHA. I think we can have it fixed for next year.
Family memberships require you to register at the same time with the same info. You enter everything, except the second name, once. So my wife and I entered that way and she had city and club and I did not. Sounds like a consistent flaw in the process.
An unrelated family membership flaw is that you can only put one BJCP number so my wife will have to bug Gordon to get CEP points (which I assume is the only reason they ask for it). I assume there are very few family memberships with more than one BJCP member on them, so maybe it isn't worth fixing.
