Are you sure you have a neutral at the switch - you would normally have live (L) and switched Live (~ with the arrow) at the master and then the three strappers going from the master to the slave as per diagram.
It sound as if you have two reds at the master one of which will be the live and the other the switched live - are you sure you have them the right way around?
