A-5 RT problem

Accorrding to the A-5 "manual", it says that if you turn the RT screw all they way in, it should be very hard to pull, if not impossible to pull.  Well, mine is quite the opposite, in fact.  The Response Trigger only works (working meaning that the "sweet spot" can be found) when the screw is turned all the way in.  As soon as I turn the screw just a little bit counter clockwise, it suddenly becomes semi-auto.  And the sweet spot is gone.  Seems to me like my response trigger is working "backwards".  Any adive on how the fix this?

P.S.  This gun is brand new.  I've only used it once at a real field so far.  Though I've had to take the gun apart many times because something is always going wrong.  At one point one of the parts... "fell" on the ground but it never seemed to affect how the gun shoots paint.  Hope I didnt damage anything.
