Y -Axis inverted with Logitech USB controller

[ZeroX4]

So today I was setting up PPSSPP controller mapping, and I noticed that the Y - Axis for the controller is inverted. I've checked and it works fine in other programs. I've also tried both using the "down" input in the up analogue space, and the "up" input in the down space to try to "cancel it out", but this doesn't work either. This shouldn't be a problem because the controller is just a standard USB one. I've tried everything I can think of to no prevail.

if u cant find solution to ur problem

this would be good workaround
