I have an AltaLink C8055 and the scan to folder entries in the address book have quit showing up on the copier. They should up in the web interface, I can add new ones and delete old ones, but they don't show up on the copier itself.
I searched the knowledgebase and found some solutions that may be helpful in getting your network address book to display on the control panel:
