You are likely running an older version of ODK Aggregate and somehow data has been inserted twice. This often happens on App Engine installs and the easiest way to fix it is to follow the suggestions at https://github.com/opendatakit/opendatakit/wiki/Aggregate-AppEngine-Troubleshooting#repairing-a-filled-in-form-submission.
