Transferring Books on CD to Z5

[BJL]

I'd like some help in transferring books on CD to my Z5. Sometimes, the digital label on the CD changes from CD to CD, within the same book. Some list the title and author, while others just come up as unknown disc. Though I can transfer these CDs to the Z5, and even change the title, the Z5 still goes back to the original CD label. Therefore, it attempts to play track one of disc one, then track one of disc two, etc, rather than all the tracks of each CD then go to the next CD. Does anyone know how to input these CDs, so that they play in the order intended?
