My problem sounds a bit different than yours. My problem wasn't that it was only charging sales tax in MO [because that is correct for MO]. My problem was that the city tax was being added and my business is not in city limits so I am not required to collect for the city. I was trying to do an override for that issue. In your case, I think it may be working correctly as in many states you do not have to collect [or pay] sales tax for online transactions for other states. You will need to make sure your states is one of those states.
