If you log in again, do you still see the form? If you do, what message did you get when you delete the form from the dashboard? Also, would you mind email me your original PDF that you used for importing to firstname.lastname@example.org.?
I don't see the form now so I am all set. I will email you the original PDF shortly via separate email.
Your forms contain duplicated value for two radio groups. I had corrected them and emailed you the corrected forms. Please let me know if you are still not able to import the forms I sent you.
