Voting machines in Pennsylvania were registering straight Republican votes as Democratic votes, officials say.
The error was due to a calibration issue in Lebanon County’s voting machines, where five machines out of the 270 machines available in the county malfunctioned, Penn Live reported.
Voters saw the errors after they reviewed their ballots before officially filing them.
When questioned about the issue, none reported their votes were incorrectly cast, according to Lebanon County Election Director Michael Anderson.
Anderson said the issue was fixed and there was no indication that anyone’s votes were incorrectly registered in the system.
Other states have also reported problems with their voting machines on Election Day.
In Utah, poll workers have had to resort to paper ballots because the machines in Washington County faced a programming problem.
In Texas, a computer used by election clerks at a Houston-area polling station malfunctioned and voters had to be sent to another polling station two miles away.
