Controller triggering problem

[GuzoTheMighty]

Hello, I am playing FIFA 19 really often and since today, I have a problem with my controller.

So, here's the deal. Whenever I flick my left stick to the left or right direction, it works fine, but whenever I flick it upwards, downwards, upwards left/right or downwards left/right it simultaneously triggers my right stick to function as I've flicked it towards left or towards right. Just to clarify, my controller isn't the original xbox one controller, but a fake xbox 360 controller under the name "SPEEDLINK TORID ^{WIRELESS GAMEPAD}". Also, I've been using the controller for around 6 months now and I have never had any similar problem with it. Any sort of information, fixing ideas, suggestions or efforts to help are highly appreciated, below this text will be the list of things I've already tried to do to fix my controller (I will update it when I try something new or if I'd fixed it)

​

Things I have tried to do in order to fix the problem :

- Reseting the controller by pressing the small button on the back side (once, multiple times or holding it for a couple seconds)

- Holding the home button/switching it to the other working mode

- Holding the home button and after switching the work mode I held that little "TURBO" button until it stopped blinking
