Address Book: Last Import not showing records

[dj]

After importing vcards from Entourage into Address Book I would like to put the newest batch of cards into a separate group. I can create the group file easy enough but when I click on "last imports" the folder is empty. I have imported thousands of records and the "last imports" folder remains empty.

Am I suppose to do something besides click on the "last imports" option to see them? Or is something not right?

Thanks much!
