I would suggest making sure that you are controlling your right stick properly. What I mean is that when you are trying to kick it right so that the wind will carry it left, you still have to get your accuracy in the correct position when pushing up on the right stick.
So for instance, you push down on the right stick to start the kick, then as you push back up on the right stick you will have to move the right stick up and to the right where the cone is in your kicking meter. If you go straight up or too far right then your accuracy will obviously be off.
If you already do this properly then im not sure how to correct this as I havent seen any problems with accuracy on kicks. I would maybe suggest checking your controller to see if maybe your analog sticks are somehow damaged or not functioning as they should.
