A320simpilot001

ive now finaly joined the SU15 beta and i was insanly happy with the fact that i ccan fly the inibuilds a320neo which i immediatly fell in love with ive been testing and flying it latley but the reversers do not seem to activate or work with the TCA airbus captain pack (the reversers work normal on any other aircraft) ive tried calibrating my trust levers dint work i tried to calibrate my throttle via the EFB but still the reversers dont activate. any idea how to fix this? or if this is an hardware issue inibuilds must fix this.
