the central official tally, and unknown numbers were added to other contests in the central official tallies. The investigator found the same had happened in 2010. There were also votes lost by garbled transmissions, which the state election commission saw but did not report as an issue. 49 machines reported that their three internal memory counts disagreed, an average of 240 errors per machine, but the machines stayed in use, and the state evaluation did not report the issue, and there were other error codes and time stamp errors. In a 2017 York County, Pennsylvania, election, a programming error in a county's machines without VVPAT let voters vote more than once for the same candidate. Some candidates had filed as both Democrat and Republican, so they were listed twice in races where voters could select up to three candidates, so voters could select both instances of the same name. They recounted the DRE machines' electronic records of votes and found 2,904 pairs of double votes. In a 2015 Memphis, Tennessee, city election, the central processing system lost 1,001 votes which showed on poll tapes posted at precincts: "at Unity Christian ... precinct's poll tape ... 546 people had cast ballots ... Shelby County's first breakdown of each precinct's voting ... for Unity Christian showed only 330 votes. Forty percent of the votes had disappeared ... At first it looked like votes were missing from not just one precinct but 20. After more investigation, he appeared to narrow that number to four ... In all, 1,001 votes had been dropped from the election night count." In a 2012 Shelby County, Tennessee, (Memphis area) election 801 voters signed into a polling place, and only 293 votes were recorded. In another precinct 20 extra memory cards were uploaded before polls closed. The central election management system let the number of memory cards be changed by hand, and reducing it could erase memory cards which had been loaded. In a 2011 Fairfield Township, New Jersey, election a programming error in a machine without a VVPAT gave two candidates low counts. They collected more affidavits by voters who voted for them than the computer tally gave them, so a judge ordered a new election which they won. Errors from 2002 to 2008 were listed and analyzed by the Brennan Center for Justice in 2010. Errors before 2006 were listed by the Electronic Frontier Foundation in
