After registration and plan selection, the membership plugin doesn't forward the user...

Sorry but I just upgraded to membership 3 and I can't seem to get it working. A user can register and then select the plan that they want to use. Once they selected the plan they should be sent to the members home page but it just defaults back to the sign up.

What I am doing wrong?
