Ok, understand on CA
Unfortunately, I can't really set it to any state as the code is dynamically used for each state depending on the variable passed at calling of the page. But I know understand why is shows CA. I might set default to be our main address in IL then.
The Texas/Wisconsin issue seems to be that 54701 and 54703 are not being recognized as Eau Claire, WI zipcodes, though 54742 seems to work. Not sure if the other zip codes are similar to something in Texas.
