For epubs, the Kobo firmware only reads the first "dc:creator" in the OPF. But, calibre writes each author as a separate dc:creator tag. Hence, multi-author epubs show up on the device with only the first author showing. This can also lead to the book on the device matching back to the calibre library when the device is plugged in. I have always assumed that kepubs work the same way, so I have never checked.

I know of a couples of ways to get around this. Firstly, after the book is on the device, use my Kobo Utilities to set the correct authors in the database on the device. That doesn't change the actual book, just what is displayed on the device.

The other is to use a metadata plugboard to set the author during the send to device. There has been discussion on this in the Kobo forum and there is a good example there to use. It's been a while since this was last discussed, but hopefully a search will find it. It's possible that you already have this set for metadata plugboard for the extended driver. That would explain why it works for kepubs.
