CH Throttle slider fails after using the slew key “Y” while other peripherals function correctly

On multiple occasions while flying in group trips after using the slew key “Y” the throttle “Slider” function is disabled on my CH Throttle while all the other controller buttons still work. One might ask “Y’ does this happen? All flight settings to easy in case of crash during group flights. Half the time the slew key works normally but the other half the time I am left without a throttle slider.
Hardware: CH Throttle, CH Fighter Stick, Track Ball, and Keyboard.
Note: No other similar failure of throttle slider in nearly 200 hours of normal flight [set on hard]. Only certain issue found with my CH Products has been caused by double binding keys which is not the case with the “Y” failure.
