I hope someone can help me. I just installed a Flight Deck and have programed in all the gears. For some reason, the rear gears display in reverse. I have Ultegra 9 speed on the back and the range goes from 12 - 27. When I am on the 12, the Flight Deck says 27 and fills in the large circle. As I shift gears, it shifts one for one. If I shift up, the Flight Deck shifts down. Anyone ever seen this one before? I have tried resetting, taking the sensor off of the shifter and then shifting to the other gears, but it goes right back to the same thing, basically showing the exact opposite of what gear I am. BTW the front works great. HELP!!!!!!!!!!!
