How exactly do you mean the state of Mexico is called California? I've however seen Mexico form in California, if that is what you mean. But the actual California state is the current day, California. I didn't chance any states in North/South America, except the Spanish setup.
As for the pops, only western Europe, the Baltics and Austria-Hungary have been done so far but even they aren't final yet, so yes it can look weird sometimes.
