Weird IR Flick in the opposite direction

[NicoBD]

Hello,
i have this weird problem: when i push the analog stick of my controller to the right (the analog stick is mapped as an IR input),
it flicks for a second to the right and then it goes to the left. i checked my controller, but that only happens with Dolphin.
my Dolphin Version: 5.0- 10262, im using Windows 10 (if that helps)
