What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
When you enable the "Headers and Text" in your submission viewer it should also show up in your pdf.
If you already downloaded the pdf and it's not there then that means you will need to re-download it again to see it updated.
I tested this and can verify it is working as shown in my demo screenshot below.
Please try it on your side and let us know.
