In the booth, I pressed the button to select Trump/Pence. The light that went on highlighting Trump/Pence. I moved on and voted for other candidates/ballot initiatives. When I reviewed my selections, the Trump/Pence ballot was no longer highlighted. The buttons were spaced inches apart, and I'm not spastic. There is no way I deselected Trump/Pence. I reselected Trump / Pence and pressed the button to capture my votes.
