The cable may be too tight. The lever on the actuator should be facing down at about a 45 decree angle. Also,, have you cleaned out the actuator, checked the condition of the #10 ball, assembled with fresh, clean grease?
Also, the bottom ramp that the three balls ride in has a notch that should be over the corresponding tab in there.
You might of just adjusted wrong. Make sure the cable is fully slack and loose before adjusting the release mechanism. If you start with any tension, the ball ramp isn't in the minimum position, and you pull too far and the balls jump to the next ramp.
Their need to be slack in the lever too, so that you don't over pull the mechanism.
They are a pain in the butt to adjust, it takes a feel for the right amount of friction and turning, but they work well when adjusted, and stay adjusted quite a long time.
