In Outlook 2007, my default "File As" format for contacts is:

"Last Name, First Name (Company Name)"

However, for several of my contacts instead of appearing as:

Smith, John (ABC Products)

the "File As" field appears as:

Smith, John, ABC Products

This is driving me nuts! All the normal fields (First Name, Last Name,
Company Name, etc.) are already populated correctly. Anyone have any
suggestions? There is some sort of formatting applied to each contact
individually in this case. But how?
