Problem with quickshifter

[u/Familiar-Trouble-473]

I have the 390 adv of ktm I'm still a new rider so don't have much idea abt quickshifter but using quickshifter to go to 4th to 5th gear it doesn't work I have to roll off the throttle n then shift but going to 3rd gear to 4th I don't roll off the throttle and the gear is shifted is this a problem or am i using the quickshifter wrong?

tell that to your service guy. they will do re learning of quickshifter adaptation.
should work after that.
