Why does the photo upload in edit mode not complete?

We are trying to upload photos to a report after it has been originally submitted but the upload never finishes. It continues to displays Please Wait for a long time. This occurrence is with Studio 620641. The same result happens when trying to upload files post original submission via the edit link in the RBC confirmation email.

Thank you for contacting us.

I was able to reproduce a form submissions issue which seems to be caused by a blank widget field which is the last field on your form.

Please remove mentioned widget field, and then try to submit/edit the form again.
