I seldom use the QS on my 2018 SP but when I do, it works like butter and I can't even feel that it was there.

Stock bike and OEM QS, with 190/55 rear tyre. No issues even once with the gearbox or QS. Fast track action, fast street and some touring.
I have seen on track days that some guys have issues with false neutrals on the SC77 bikes. I did swap bikes once, got zero false neutrals on that bike also. The other guy somehow managed to get false neutrals on my bike also. I wouldn't count out rider error Maybe let one of your friends ride the bike and see if he/she gets false neutrals too?

Sensitivity of the QS needs to be adjusted, may be?

For your convenience, here is the 3rd gear.
Looks like it's more for tracking and heavy abuse scenarios.
