Bug InputAction.AddCompositeBinding causing errors.

I'm going crazy here. I'm trying to bind controls at runtime and found this method in the documentation:

Code (CSharp):

1. moveAction.AddCompositeBinding("2DVector")
2.             .With("Up", "<Keyboard>/w")
3.             .With("Down", "<Keyboard>/s")
4.             .With("Left", "<Keyboard>/a")
5.             .With("Right", "<Keyboard>/d");

It works as expected for every key except the "Right" action, which is not registered and throws these errors:



This problem persists no matter what key codes are entered (they were bound to the arrow keys when that image was captured).

Oddly if you duplicate the assignment of the "Right" action;

Code (CSharp):

1. moveAction.AddCompositeBinding("2DVector")
2.             .With("Up", "<Keyboard>/w")
3.             .With("Down", "<Keyboard>/s")
4.             .With("Left", "<Keyboard>/a")
5.             .With("Right", "<Keyboard>/d")
6.             .With("Right", "<Keyboard>/d");

It behaves as expected, but still throws the same errors when the "Right" action is pressed.
It seems this is a problem with the input system code itself, unless there's something I'm missing that wasn't included in the documentation.

 

Update:

Adding another binding to the input action asset seems to fix the problem, but I will be leaving this up as it's still a bug, one of many that make the Input System feel overall unpolished.
