1=> For terms and conditions, seem something conflict on your site and it causes the issue. The terms and conditions is supposed to open on a nice modal popup. So in this case, please submit a support ticket sending us admin and FTP account of your site so that we can check and solve it for you.
2=> For the state field, I think we could not solve it. The reason is that the value of the state is two characters, for example, IL instead of Illinois. I guess it the CB, you entered Illinois (long state name) and It causes the issue. Try to enter state code instead of state name into your CB profile and it will work well !
I have the same issue with the terms & conditions which do not open in a new window or popup. Can you publish the solution in this forum please so that I can do the same on my website?
