    Hello campupwards,

    I'm sorry for the trouble caused to you.

    I did test your last edited form and I am able to replicate the issue you are having. The issue seems to have caused by the google drive integration you have in your form. I would suggest you to remove the google drive integration from your form and integrate it again. That should hopefully solve your problem. 

    Do get back to us if the issue persists.

    Thank you!
