Again, when clicking back during the registration process and then, again, proceeding to the next step, I can see two thank you meggages and in the back-end I can see two records, althoug one of them is without price and booking number.
I too am getting double records. However, I did not click the BACK. I just completed the process normally and got two records and two email notifcation to both the user and the admin. [2.7.1.c]
