OK, I’ve figured it out! The confusion wasn’t your fault at all–I had hacked my versions of the extensions to compile, and I didn’t update the version number. The background is here; Inform changed the way it handled blank table columns, so you need to take the tables that are defined with a kind name in the top row and move them to the heading.
Unfortunately while testing this I downloaded the versions of the extensions from the website and they overwrote my working versions. Also unfortunately, Michael updated the extensions himself, but they were uploaded on his personal website which is now gone. But there may be some people who have the extension and could upload a working version (you could try PMing paulobrian or Joey Jones).
