Yes, sounds like you have unfinished, unused, abandoned, or non-working field map layout(s) for the same form that also have email attachment checked. Go through all other field map layouts for the same form and uncheck the email attachment option. Or better yet, delete all unused field map layouts by selecting the layout – scroll to the bottom of the layout and click “Delete Entire Field Map”.

Then, let us know if the issue is resolved. We remain at your service.
