Set mouse speed not work

macOS: 10.14.2
btt: 2.697

I try to reinstall, but
I change slide bar low or high
my magic mouse 2 speed never change

I get the same behaviour. Moving "Set mouse speed" slider for Magic Mouse 2 never changes the value at the end of the slider.

MacOs; 10.14.2

Macbook pro 13 inch 2018

Use this amazing solution:
Open Terminal and enter this:

defaults write -g -float 5.0

Then hit enter, close Terminal, restart the Mac.
