Quit calibre. Plug the reader into the machine. Using a folder browser, navigate to the removable disk that is the reader. Work your way down through (if I remember correctly) database/cache to find the file media.xml. Delete it. If you are working on a storage card, delete cache.xml. When done, eject the reader. It will spend a long time rescanning all the books and rebuilding the file(s) you deleted. All collections and bookmarks will be erased. Note that you will also lose author/title information for any book that doesn't have built-in metadata.
While you are there, and assuming you are downgrading, you might as well delete the .calibre.metadata file. Calibre will rebuild it, and you will avoid any confusion caused by the downgrade.
An alternative way to do it is to transfer the books again using the downgraded calibre. It should rebuild the collections for those books, and delete any collections that are now empty.
