Dobot M1, change the collision detect


I have change the collision detect. From Low Level to High Level with a payload 0,25kg. After i click enter was shows -0,75kg. After the DynamicSetting, works the dobot M1 correct.
Now i would like change the payload it again. But in the SafeSetting page can i not die Payload change.
I change it to zero, for run the DynamicSetting, but after click enter, the old value show again.
Can i with this Payload the DynamicSettings correct run?

Thanks and regards.
