One quick way to isolate this in PPSSPP: open Settings > Controls > Control Mapping and watch which rows highlight when you move only the left stick. If the D-pad rows also highlight, you have overlapping bindings, not necessarily a bad controller. Clear the D-pad bindings, bind them to the hat/buttons, and bind the stick only to the analog axes. In Sixaxis, also remove any profile rule that maps stick movement to D-pad buttons. If only the stick row highlights, the double input is likely happening in Sixaxis or its profile.
