Synchronizing iBooks with iPad/iPhone does not synchronize collections

books

When I synchronize iBooks from my MacBook to my iPhone/iPad via iTunes it synchronizes all my books, but it doesn't synchronize the collections (they are all just dumped into one single collection).

How do I synchronize the collections?

EDIT: the `Settings -> Synchronize bookmarks, highlights, and collections across devices" option is enabled.

Go to Settings/Ibooks and turn on "Sync Collections" (also sync bookmarks and comments if you want that too).
