Perhaps the "note" format is simply broken? The linked style guide for...
"Chicago Manual of Style 16th edition (note) Chicago format with short notes and bibliography
chicago-note-bibliography-16th-edition.csl | Style Guidelines" (http://www.chicagomanualofstyle.org/tools_citationguide.html)
...says that it will provide a number...
Each note corresponds to a raised (superscript) number in the text"
...but what actually happens, both in the preview and in my Google Docs Document, is that the full note goes inline with the text, and then the bibliography has no numbers; it looks like this:
