"Call for Help Range" problem

I need to adjust help range of neutral creep so I tried at Gameplay Constents for "Call for Help Range" and "Call for Help Range, Creeps" but both of them did not adjust any help range of neutral creep.

Question : How can I reduce help range of creep? (Help range is when you damage creep they will call nearby creeps to attack you)

I think the (Attack fields) Acquisition Range might also play a role, have you tried altering that?

Yes I have tried it. It changed about range of neutral creeps that they will start attacking nearby foes.
