Sounds Not saved correctly

Sometimes when I load a Kit I find a sound having its oscillator turned down to -64. Therefore no sound comes out until I bring it up, back to life.
Or in another occasion the filter set differently than how I saved it.
Does anybody know what the problem might be?

Have you used the performance feature with this kit?
