this controller seems to have different modes.
try with another mode (look up the manual, i guess it has x-input and d-input mode, or pc mode, android mode, ps3 mode etc..) just activate another mode of the controller, reconfigure the buttons in the menu (Controller Settings) and try again.
if there are still issues… well, then i would suggest to buy other controllers with better quality (original Sony PS3 controller, or Microsoft Xbox controller or 8bitdo controller). they cost more, but they have better quality and will work without issues.
