Probably a dumb question, but I can't find the solution yet.

In my calibre libray I have several versions of the same book: for example I imported a mobi book and converted it to epub, I imported an epub and converted it to pdf and mobi. The all show inthe library correctly.

When I 'upgraded' my Cybook Gen3 to support epub I used calibre to send them to the device (having deleted the original mobi content to update the folder structure from calibre). Now I have reverted to the mobi firware and find that the only version on the Cybook is the epub, I can find no way to select which format I send to the device and resending just puts epub back. I don't mind having multiple versions on the reader as the firmware will only see the ones it is 'allowed' to read, but can't seem to get any other type transferred.

I have got around it for now by manually copying from the library to the device, but would appreciate any info on what I did wrong.

Thanks in advance.
