CustomProcessor doesn't run when Axis value is zero

I’m trying to create a custom processor that converts an axis from [0 to 1] to [-1 to 1].

public override float Process(float value, InputControl control)
{
    return (2f * value) - 1f;
}

I currently have it mapped to a pedal and when I lift all the way off, the value goes to 0 instead of -1. I put some breakpoints in the code and I noticed that a breakpoint never gets hit in the Process() function when the value goes to 0.

For more context, I’m trying to have a single Action that can be mapped to either 1 pedal or 2 pedals. If one pedal it goes from -1 to 1. If two pedals, one pedal goes from 0 to 1, the other goes from 0 to -1 (Using a Custom Composite). This is to control the front wing (canard) on a hydroplane.

Bump, I’m also trying to create a processor to just invert the axis value (I had to use a custom processor in order to allow user to enable / disable inverting the axis), but that does the same thing. If there’s no input happening it just returns 0 instead of the processed value.

Am I missing something? Or is this a bug?
