This is the same behaviour as the mod portal (and the game presumably uses its api for this). And its why you should upload older version first, then newer version. As a workaround you can take down and re-upload the latest 2.1 version.

Actually, I was wrong. It was pointed out to me that the mod portal API provides this information from parsing the mod info.json. So, this is now fixed for the next release.

Planetary Pioneers was originally created prior to 2.1. You probably are running experimental, and expecting the mod pack to work in that version, which it cannot (yet).
