Viewing series number on Kobo Glo HD

Hi,

I've just bought a Kobo Glo HD, and am using calibre to put some epubs on it. I've used the goodreads plugin to add series information (including series, and book number within the series). I've also created some collections roughly based on book series. I've seen pictures on the web where the book listing on the kobo shows the series number under the title/author - yet mine doesn't do that. Is there something I need to do on the kobo to view the series number? Or is there something in calibre that needs to be changed?

Thanks!
