Deleting a document leaves behind the terms, which end up with a 0-length list of documents. Facets include these terms. After you delete the documents, run an optimize and these "orphan" terms will disappear.
That is why you find '1996:0' in your index. However, I don't know why you would get a '0:0' if you never indexed year '0'. If this still happens after you add an optimize pass, please raise an issue in JIRA.
