Title says it all, there are a ton of buildings that have no description at all besides their name. Are these just unfinished, or did I install something incorrectly or what?

Which buildings? Some, like Stables, have no description because all they do is allow you to build mounted units in that city. (Most units have building prerequisites.)

The Planer Gates for example, the buildings under necromancy and the other techs right before sorcery, those are the ones that I noticed and can recall off the top of my head.
