Issues with 360 controller and PPSSPP on Windows

[Satin]

So I have the latest build and all that, jazz before you ask. But here's my issue, so whenever I hold down on my analog stick it doesn't seem to be completely read ingame, for example in Metal Gear Solid Peace Walker, Snake will walk instead of run, but if I slightly tilt it to the right or left, he'll run diagonally back to the right or left, not sure why this happens but it's kinda annoying, does anyone know how to fix it?

Tried another game too, Kingdom Hearts Birth By Sleep, same problem, Ventus walks backwards slowly.
