"Step size" option doesn't work after i alter it

[skxmxm]

I try to change the "step size" but found it still the same. But "Arrow key step size" can be changed succesfully. Seems like the "step size" is always set to "100" no matter how i change it.
I use edge as my brower and logitech g502x as my mouse.
