Please excuse the stupid noob type question, but I'm just starting to really get to grips with all that Calibre and its plugins can do.

How do I use this plugin to create collections on my Kobo Clara? I have "Create Collections" ticked, not sure what I should put in the "Collections colums" box. It says "specify I tags type column for automatic management" so I entered

Series

but after that, nothing seems to have happened. The book I want to transfer all have series metadata, and I have selectred "update metada on device", but I have no new collections on my Clara. I know the fault is mine, what exactly have I done wrong, or failed to do?
