Hi,
I have cloned your form and the issue happens due to users refreshing the thank you page after submission.
I would suggest trying one of the following:
- Enable Unique Question, this way only unique answers for a certain question can be submitted.
How-to-set-Form-Limits-Based-on-a-Unique-Question
-- Add a Captcha field:
- Redirecting to a custom thank you page on your website.

Please try the above fixes and hopefully you will not receive any further duplicate submissions.
Let us know if you require further assistance.
