Hey Karl,
There is nothing you can do other than going into the local address book database and select Tools > Preference and click on the "Update all entries" button for now. Future BES software should peek into the server replica copy of the NAMES.NSF's profile document "DirectoryProfile" and grab the user's preference and the evaluate the "NameDisplayPref" value so that your newly created entries from BlackBerry are displayed correctly.
Anyway, it is not a critical issue... I would say that it is more serious when your newly created entries from BlackBerry cannot even sync to the address book
Let's wait for any SDR and see when this will be addressed in the future codelines...
Cheers
