You still have Season 1 as a fully-fledged Steam (DLC) purchase, recognised internally within the client; it's just not shown in the traditional and most sensible way. I'm the same with the first two, and the third is listed. That both Farsight and Valve haven't come up with an adequate solution to this after many, many months (and hide from the subject) is a little shaming, though, and I certainly expected more.
