smoothing modifier - locked weight and secondary weight unlocked after new loading the scene

Is it not possible to inject the smoothing modifier to a figure, fix the values memorize them, lock them and memorize them locked, save the scene and load it new and they are still locked? each time I load the scene new the weight and secondary weight of the figure are unlocked the values are like I fixed them but not memorized so if I do not think on this and memorize the figure during scene creation I got the original standard values and my fixed ones are lost.
