Left Analog Stick not working properly
I was playing Super Smash Bros for Wii U and Hyrule Warriors during my winter vacations, when I wanted to play Hyrule Warriors, everything was fine but when I let go of the left analog stock (like say... let it go from up or down directions) the character (Young Link) did a mini-step to the left, I did this many times and 9/10 did move to the left a little bit. Then I tried Smash Bros., I dashed and let go of the stick and the character (Mario) faced left, again, I tried several times and now 8/10 faced left.
What can I do to fix this?
I already tried Re-syncing the controller and resetting it by pressing A, B, + & - at the same time, but none of the methods worked
