"Get Action Mapping by Name" array not returning any Gamepad Special Right/Left keys?

I’m setting up some control rebinding for controllers, and everything works perfectly aside from any inputs that are bound to the “Gamepad Special Right” and “Gamepad Special Left” keys. The Get Action Mapping by Name seems to not register these two keys as legitimate inputs.

This image shows what I have set up. The “input” variable is a enumerator of all gamepad keys, which are set elsewhere.

Is there something special about these two “Gamepad Special” keys that prevents the node from registering them? I’ve tested the actual rebind mechanics with them and it all works, I can bind to and from those keys. I just can’t access the key name (which I need for some UI aesthetics).
