Sneak and Fly-down controls cannot be placed in the same position

With the D-pad and Tap to Interact control mode, Customised Controls and Swap Jump and Sneak, I've noticed in this newest update that the Sneak and Fly-down position cannot be placed in the same position. In previous versions, although I could be remembering incorrectly, the Sneak and Fly-down controls would be represented by the same button "object"; both functionalities were represented by one button that would switch. Like other platforms, it's useful to have these functions set to the same button. Now whenever switching between flying and standing, the button moves, which makes basic gameplay very inconvenient.

I've tried place them in the same place but collision detection prevents that, especially since there's still the invisible button present from previous updates, while editing flying controls.
Even if I do manage to get them into the same position, they automatically move back, during gameplay, by switching between flying and standing.
