How do I have my Kobo (Forma) allocate books into shelves in accordance with how they are listed in Calibre?

Calibre seems to pick up some of the books as existing on the Kobo and some not.
It has successfully 'shelved' some, but about 90% not.

Is there a way to ensure all are shelved correctly without adding them one by one?

Background

1. I put a bunch of books onto the Forma, most of which I already have in Calibre, with shelves in the metadata as one of the columns

2. I have them in different folders on the Forma, cos sometimes I use Koreader

3. Some of them are correctly shelved, but 90% aren't.

4. Some are picked up in Calibre as existing on the device, most aren't.

5. Dunno if relevant, but: they're already allocated to shelves in Calibre because I had many of them on a Kobo Libra. But I dont want to use the folder structure I used on that, because I've redesigned it.
