Oddity in the vote counts

A surprising result from West Union means that the town is going to have to decide which of its four council winners get four-year terms and which get two. There were four unopposed ballots candidates for four council seats. And the unofficial results show Kathy Frederick, Bethany James, Dixie Meeks, and Doug Moore each with 15 votes. There were no write-in ballots cast. How to solve it? An election official said maybe a coin flip.
