Easier testing

Hello – I am configuring and testing Lucky Wheel. The default time is 24 hours to spin again. I want to change that to 1 minute so I can continue testing. I have changed the setting to one minute but the popup icon is not appearing. How can I reset or erase data so that I can continue testing. Once it is ready I can change it back to 24 hours.

Also – can I use a custom image for my popup icon? thanks.
