SC2 key pressing repeat rate doesn't match with REGedit

Recently, I have enhanced the speed of rapid fire in registry editor. It’s working outside the game very well, but in-game I have been experiencing much slower repeat rate.
Here’s my changed settings in registry edit on my Windows 10 laptop.

AutoRepeatDelay=250
AutoRepeatRate=1
BounceTime=0
DelayBeforeAcceptance=0
Flags=59
(others are all 0)

Since then I noticed Filterkey has been activated. If I change anything in it, it resets my settings, kinda messes up. Afterwards I change from Registry to get back into my preferred settings.

I am hopeless at this point, I could find nothing. I’m not even sure if it has anything to do with “FilterKey” or the game settings. I would appreciate anyone’s hand on this.
