First Contact achievements are not working

Exactly what the topic says. I've jumped into SCO, and I'm a bit overwhelmed by the number of the things to do here.

So far, I've met the Tywom, the Scryve, the Mysterious Aliens, the Mu'Kay, the Drenkend, the Norast, and the Kzanti, but none of the First Contact achievements have been unlocked yet.
