Blindwrite 2 sessions help

I've burn Msr selfboot (2 sessions disc). The burn was succesfull but... My copy has 3 sessions ! What can i do for having 2 sessions like the real selfboot ? Does an option exist in blindwrite for that ? please help !

what do you mean you burnt it, is it a backup, because you can't burn an original,
