As noted in this article you can run into problems when submitting forms multiple times from one device as HubSpot defaults to using coookies. There is a new option called "Always create contact for new email addressses." which was implimented to solve this exact problem. You'll find it towards the bottom of the options tab in the form creator.
Let me know if you have any questions or if this solved your problem make sure to mark the thread so others can find it.
