MIC issues

I've noticed while playing as the Selukids that some of their iranian provinces dont seem to allow me to recruit the units I should be able to according to its government type. For example, a maxed out factional MIC in syria lets me recruit just about everything, while in Persopolis I can only recruit the most basic native spearmen, native levy pahlanxes, and seige equipment. Both are Type I homeland governments. My local MIC's in Persopolis gives me a greater variety of troops, as if Persopolis was a type III or IV government, but its got the type I government built there at the start, and it has the homeland resource in it. Bull-dosing and rebuilding either th government and/or factional MIC in Persopolis has no effect. The same thing is going on in the other Iranian provinces. Upgrading from type III or IV governments to type II has no effect, its like their locked into the lower quality government types. Am I missing something here?

Certain Seleucid units are Macedonian units and can only be recruited in places that have been colonized by the Macedonians (places where Alexander's soldiers settled down after he died). There are alot of Macedonian settlers in AsiaMinor, Syria, Egypt, and Babylonia; though in Iran, you are left to recruit from the natives and therefore not a whole lot of elites. Unfortunately you cannot set up Hellenic colonies where you want.

And of course couple this with the recruitment system that is full of holes.

During mine Epirote campaign I've noticed that I can recruit Chaonion Agema in the city of Thermon.
It seems illogical since I can't recruit Pezhetairoi there.

I have noticed that in a few provinces I cannot recruit the Native Phalanx. Most of these provinces are in the east.
