You didn't install the beta III then, this is an error which is probably due to the former beta II settings for troop trees. Is faction names and lords are the native ones too ?
If yes, you might want to make sure you installed the beta II, and maybe the beta III properly. I'm pretty sure nord troops are correctly set to british recruits, which can only upgrade in british troops.
So the game might allow you to recruit higher troop tier in village but it will be calculated over british recruit troop tree, therefore you can't get "nord" troops.
However beta II has missing troop update so it's possible to get rhodok troops for example, beta III correct this issues amongst other things.
