Carthaginian MICs

I'm not sure if this is a bug or if it is supposed to be like this but in my Carthaginian campaign I have noticed that beginning with the level three factional MIC there are several units which are described in the building description but are not able to be recruited once the MIC is complete. The units include Iberian assault infantry, Liby-Phoenician heavy spearmen, and heavy Libyan spearmen. Can someone please explain this to me?

Those are reform units. The exact requirements should be in the FAQ.
