    Sorry for inconvenience this may caused you. 

    I am not exactly sure how this has happened. Maybe your user did not closed browser tab in which form was filled and somehow form was resubmitted, most likely by using back browser button.

    To prevent duplicate submissions you can set unique submission on your form:

    You can also set form limit based on unique question:

    And you can add a captcha to your form:
