A KH recruitment question

[HopliteElite]

I am playing Koinon Hellenon (obviously) and I just have a quick question about hoplitai recruitment. In Chalkis, a subjugation region, where I have a type III government, I can recruit classical hoplites, yet in Pella, another subjugation region, also with a type III government, I cannot recruit classical hoplites. Both cities also have an equal level barracks. Is Pella just an odd city, like Sparta, that has akward recruitment potential? By the way, I'm having a blast and have yet to come across one bug in .81 so thanks for the great mod, I just can't stop playing.
