Building types missing in project list after flipping

I'm currently playing GalCiv2:TA 2.02 and the Korx species and I have encountered a weird problem which I have noticed in a few games before.

In this specific case I'm getting a planet through "flipping" i.e. planet rebelled and joined my empire.

Immediately after that event I removed some unnecessary buildings including a Fusion Power Plant.

A bit later I decided to turn it into a manufacturing planet nevertheless but this time I couldn't pick any power plant type from list, they were all missing altogether. It happened to me in a few other games as well, I removed some building types  just to find them missing in the list later when selecting that planet again. I've additionally noticed that it affects primarily buildings like power plants.
