how does the scale parameter work in the response optimizer

I am trying to use the repsonce optmizer in simullink to optimze severla varbibles for my controller. My question is how does the scale field work? I have varibles that have a magnitude of 10^3 and others that are of 10^-1.

How can I make sure that the parameters are being choosen at good scale. I dont want my varibles of scale 10^3 only changing by only 0.1

EDIT:

I am using R2021a, I dont know why its not letting me select this verison.
