I just got my Kobo Libre colour and installed NickelMenu, unfortunately, after uploading a few kepubs through calibre, no series information is shown. How do I go about debugging this?

Edit: thats in the epub
<opf:meta property="belongs-to-collection" id="id-3">The Combat Codes Saga</opf:meta>
<opf:meta refines="#id-3" property="collection-type">series</opf:meta>

Edit: I am using Nickelseries, not Menu
