I posted about this before, but to no avail, so I thought I'd try again. For some reason, I cannot edit, view, or remove birthdays from Address Book. I can view/edit them on my iPhone, but not in Address Book. I believe I can also enter them via Address Book, but once they are entered, I can't make any modifications. The dates are there somewhere, because they show up in my birthdays calendar in iCal. I attached two screenshots to illustrate my problem. When viewing the address card, the birthday field is blank. Clicking 'Edit' provides no help, either.
