I have this issue regarding the left analog stick, not the right one, as a temp fix I'm using xpadder.

If you are using the xbox360 mappings,
try doing what I did, unmap all keys except the LAS(Left Analog Stick) in the XBOX Controller page, then set your xpadder to coincide with your what is mapped at the keyboard page EXCEPT LAS.

Worked pretty well for me. So far.
