Airbus Throttle quadrant reverse problem

Hi everybody, my name is Filippo, I live in Italy and this is my first topic. I hope you can help me to solve this problem. I'm building an Airbus throttle quadrant to use with Wilco Airbus on Fs9. I've got Fsuipc registered, but I can't make reverse works. I try with the Fsuipc joystick calibration, setting the reverse, idle and max position but the thrust goes only from idle to max. With default aircraft it works... Here a pictures of the object:
