Another Question about the toe brakes

I wanted to confirm something about the operations of the Toe brakes that does not make sense. I wanted to create a separate post so that this questions doesn’t get lost in my previous thread.

So here is what I am wondering about.
The toe brakes have a range of motion just like the levers on my throttle quadrant . When looking at the assignments of the Throttle Quadrant, The throttle, prop and mixture, have not only the rectangular box with the joystick L-Axis X ,Y and Z but there is also a slider under that with a white bar that gets longer and shorter as the lever moves through the ranges from off to full.
Since the toe brakes also have a similar movement from 0 to 100% as is indicated in the graphs of the sensitivity settings, why is there not a slider bar for the brake movement below the rect. box that shows the Axes that are assigned?

And why are there 2 rectangular boxes adjacent to each other for the Right Brake and Left Brake fields? Both boxes have the same Axis setting in them. Is that normal?

I figured out the answer to this in another post of mine.

Perfectly normal. Independent wheel brakes to assist ground steering at low speeds, particularly in small GA aircraft, especially tail draggers.
