Axis inputs mixed between controllers in build version

I ran into a problem while adding local play support to our multiplayer game, involving inputs.
The trigger keys are working in the editor, but when I build and test the triggers are either ignored or listening to another controller.
I’m testing with XBox One controllers, connected with USB cable, using official drivers. When I’m setting up the inputs it seems like 3rd axis is both triggers, negative being left and positive being right. But I want to be able to press both triggers at the same time, so I’m using 9th and 10th axis which are left and right triggers separately.

But it seems like the only time RightTriggerX triggers is when I press up with the right stick on that controller and press the right trigger on another specific controller. But, as mentioned, this is working correctly in the editor, the problem occurs when I try a build version.
This is how I check the inputs:

public enum PadAxis {
	None, LSVertical, LSHorizontal, RSVertical, RSHorizontal, DPHorizontal, DPVertical, LeftTrigger, RightTrigger
}

public static float getRawInput(PadAxis axis, int joypadID) {
	float result = Input.GetAxisRaw(axis.ToString() + joypadID);

	//temporary log test
	if (Mathf.Abs(result) > 0.9f) {
		Debug.LogError(axis.ToString() + joypadID + " is pressed");
	}

	return result;
}

Does anyone have an idea where the problem could be?

Edit: Using Unity version 4.5.5f1

Edit 2: I created a new project to see what would happened, and 9th and 10th axis did not react to anything. After going back to the real project the same issue happens in the editor as I described in the build. I’m almost certain I changed nothing in the code, so I have no idea where that came from.

2017.3.0f3 here. Yes its still an issue. Still wondering. Solution so far for me - don’t use both triggers…

Currently running into the same issue. On build only, my triggers shuffle between controllers.

Any update on this? Just ran into the same issue. Unity 2017.3.1p1,Any update on this? Just ran into this as well. Very annoying. Unity 2017.3.1p1
