I finished all my down ballot choices on candidates and referendums, then went back LAST...... and made my presidential choice. It showed it was a valid selection this time. I asked again, "Why?" And she said " WE DONT CONFIGURE THE SCREENS".
Not good folks. My wife had the exact same problem in her ballot selections.
You have drawn up a statement and had her sign and date it. We all should do that. Document, document, document.
