Analog stick wont read inputs correctly

[that guy]

I am using a dualshock 4 controller which I have checked reads inputs correctly on other software; however, with ppsspp my inputs in the north east direction as well as the south south east direction get locked into a sort of diagonal movement.

I've rebound my analog stick and have tried unplugging and replugging it into my computer with no results.

Any help would be much appreciated.
I checked for a related thread but couldn't find one that seemed related.
