Xbox one gamepad (Pro Evolution Soccer 2016)

Hello everyone, I have such a problem downloaded the pro evolution soccer 2016 myclub PC version I have an xbox one gamepad got into the gamepad settings to swap the keys. Whatever key the system presses to me, the system automatically presses the Z axis. For example, I wanted to swap the x and b keys, as soon as I select the x key, the z axis appears in this place instead of the x key.
Whichever key the z-axis is highlighted everywhere. No problem in other games !!
