Fire Mode When Zoomed will not unbind

Im trying to swap the toggle controls for the Fire Mode and the Laser/Light. I want to be able to switch Fire Modes while not zooming and toggle the Laser/Light while zooming. But the Fire Mode (while zoomed) will not unbind. Binding the Laser/Light (while zoomed) to the D-pad (down) will toggle both the Laser/Light and the Fire Mode. Please fix. Xbox Series S player.
