Why are my joysticks affecting each other?

Hey guys, so my problem is, my right joystick is turning left and right a little slower than usual, and sometimes when turning right it randomly stops, but my real problem is, whenever I hold up with the left stick, my Xbox also gets the input that my right stick is turning left so my in game character turns left much faster then when I move the right stick myself, and when I hold the left stick down, I turn right really fast.

So, why is my left stick affecting my right stick and how do I fix it? Thanks in advance
