JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I've tried cloning your JotForm to my account and see that option Hide unchecked items is not selected in the widget.
I've enabled the option in the widget and see that the unchecked items are not displaying in the notification email.
Please check the widget setting once again and make sure that the option is selected. Please get back to us if the issue still persists. We will be happy to assist you further.
The other question related to checks not displaying is moved to a separate thread and shall be answered there shortly.
