The settings you have sound correct. For things not working, can you explain a bit more about what your testing and what's happening:
* Where are you being redirected instead?
* When you say "CB Email Sign Up", do you mean they are just logging in with their regular Joomla/CB credentials, or is this some special method of logging in?
Another thing you can test is switching the "Registration Component" in the SCLogin module to "Joomla". Then, test if the redirection works. If so, it means that passing the login redirection off to CB when it handles the login isn't working properly. That could be due to a setting in CB itself or an add-on that's altering how authentication is working and possibly the redirection of the user after they login.
I hope that helps, but if not, let us know the answers to the above and we'll help however we can.
Thanks,
