Contacts not handling names correctly.
We are trying to send out a "New Year's" card. In previous years I have had no problem printing the mailing labels for these cards.
Today I'm seeing that of my contacts are printing with first name and then last name. But, many of them are printing with last name, and then first name.
I have tried resetting the Contacts preferences so that it would list first name first. Doesn't change anything. I tried creating a new group and then moving the cards into it. I moved the cards into the new group. In each card's profile, the last name is listed first then the first (as it always has). But when I move the card into the new group. It is listed there last name, and then first name. I've tried everything and end up with a group having some of the names listed first name and then last name land other name being listed last name and then first name.
How can I fix this? I have several hundred names in my contacts folder. Is there a bug in Contacts?
Thanks,
