At this point I bearly remember the details but I think there are three tiers of units _old, default and _late. I have no Idea to change the date at witch the units used change. So my general idea was to make the midgame units look high medival with the default set up but avoid plate and bascinet-helmets until the late game. But maybe something changed due to patches after all. In that case, if it's different from the pictures it's a bug.
Edit: okay the pictures are barly any help. In any case: don't get your hopes up that anything will be fixed any time soon.
