As I understand it is somehow related to two separate entries for spaceport abilities: "spaceport" and "emergency energy". the first is listed in homeworld description, the second in all other colony types. PvK, can you please look on this problem ?
The easiest and fastest way to solve this is to give spaceport some small production/research, so AI won't waste this planetary slot completely.
The Emergency Energy is what the Proportions AI looks for to build the correct space port facility. The fact that most planet types include spaceports is perhaps inefficient, but I don't know of a way to tell the AI it needs only a certain number of spaceports per system, because the AI facility construction file is per planet, not per system. If I have some planet types not build spaceports, then there is a chance that the AI won't build any spaceports in a system, which would probably be worse than building redundant spaceports. After all, building only one spaceport per system is actually kind of dangerous, because if it gets destroyed by something, then the whole system's production, research, and intelligence, is suddenly lost. As far as I know, this is just a clumsiness of the AI and not something that can be tweaked by a modder. At least, I don't know of any trick that will get it to build only, say, two space ports per system, and never fail to build at least one per system.
