Custom civs disappearing/unplayable

I am unable to start a game in Supernova with custom civs (or default civs) besides the base Terran civ.  What is also weird is when I edit a custom civ, and then save it as a copy of the original civ, the civ’s copy become playable upon a restart (but the original custom civ is still unplayable). 

What is also strange is that neither that custom civ or civ’s copy are available in the GC4 game anymore after saving the civ’s copy, only in Supernova.   While I don’t really care because I’ll be sticking with Supernova, I don’t know if this deletion of the custom civ was intended.
