Why is my contact not in my contact list of my htc hero after I edited this contact?

I just got my HTC hero yesterday and I thought I would start adding pictures to my contacts, linking them to facebook, adding birthdays, etc. After editing to of my contacts I realized they are no longer in the my contact list under the default app “People”. Now I can find these two contacts if I make a call and start typing there name but I would still like to be able to have them be in my contact list. Is there a way I can fix this without having to re-add them as a contact?
