Board editor, clear board

I'm on Android and when I go to tools>board editor > I can track pieces on and off the board but I do not see a "clear board" button or a trash can icon but some people have spoken about. How do I clear the board to start from scratch?

Here's a screenshot

Tap the Gear Icon, tap 'Starting Position' and select 'Clear Board'
