I would suggest posting some actual information. You've posted none.
Which Contacts are not showing up that you think should?
Where do these Contacts reside?
Have you configured the folder in which they reside as an email address
book?
Do the Contacts that do not appear have valid, resolved electronic
addresses?
What information store are you using?
