Reply to midi fighter deck a deck b

Hi Guys

I am new to any type of mapping! i have just recieved my midi fighter and i have followed the video to set it up with my s4, i first downloaded the firmware and updated the box, i then imported the instant gratification tsi file and imported to traktor and follow the video, ok so on deck a it works just like the video but deck B the bottom row of effects are on the top and the other buttons seem to do nothing? please help
