REV THRUST

Hello all,Last weekend I made an improvement to my self build thrustlevers. I implemented thrust reverse. A thing that I experienced is that when the reversers where pulled out of stowed position, (REV turned amber in EICAS) there is a forward thrust not reverse. Only when I pull the levers farther back they turn GREEN, then there is a reverse thrust.Is this normal or is this a FS9 thing.....ThanksErik
