This same thing happened to me in 2016. Three times I chose Donald Trump and times when I checked my choices, it flipped to Hillary. Finally, on the 4th try, it worked. Loudly told the poll workers and everyone I saw in line to check their vote before they flipped the switch to cast their vote. This was not a computer screen. It was a more like an old voting machine but it allowed people to check their vote before flipping the switch to cast.
