Kobo: 'Set series info' only works after polishing, and how to get metadata from kobo

Hi,

I have a kobo glo HD, and have 2 questions about metadata management. I've got the kobotouchextended plugin installed.

Firstly, I have series info metadata in calibre. When I first send a book to my kobo, the series info doesn't appear. However if I select polish books, then it does appear. I have 'set series info' set in the plugin. Any ideas why this would be? I notice that there are 3 plugins for kobo - kobo reader device interface, kobotouch, and kobotouchextended. Should I have all 3 installed, or could they be conflicting?

Secondly, when I've finished a book, I move it into a 'read' collection (e.g. from 'fantasy' to 'fantasy read') on the kobo. However when I connect the kobo to calibre, it moves the books back into the collection that is set in calibre (e.g. 'fantasy'). Is there a way to get it to read the collections metadata back from the kobo, into calibre? I used to have a kindle, and the kindle plugin let you sync the metadata back into calibre.

Thanks!
