Bedrock customizable controls have lots of issues but one thats bothering me now is, the creative/swim/climb up botton's 'hitbox' is seperate from its button. If you move the button in the controls, the hitbox will move but not the button. Same with resizing. You still click the the button thats there but you cant move it or change its size.  

  Steps to replicate.

1. Load up and turn to creative/swim/climb.

2. Click the customize controls

3. Move the up button hitbox. The button will not follow
