Multiple Blind Form Submissions

All of our blind forms seem to have an issue where they appear to be submitted multiple times by each user, but the user is only submitting once. We only use blind forms (today) in emails, so wondering if that is the issue? We do not see the same issue happening on forms embedded in web/landing pages.

We know the multiple submissions are not being driven by the user because they typically happen within seconds of each other, and we have tested with our own emails - submitting the blind form once and it tracking as 2-3 times on profiler.
