This is a generic answer since I am not familiar with your particular 
equipment. A derailleur works by the cable's position fighting spring 
tension. If the cable sticks then the spring will take over and allow the 
gears to shift when you don't want them too. There should be a screw on 
the shifter that you can tighten to make sure it doesn't happen.
