Is there is a setting that we can change to avoid reverting information entered on the form if someone proceed without completing the other mandatory

I am not sure if I have understood your question correctly. Do you mean to say that fields data are being reverted when mandatory fields are skipped?

Please note that if you have set the questions as required field, your users will not be able to move to next page or submit form without data input in required field. I would suggest you to please set the questions as required and that will solve your problem. The following guide should help you: https://www.jotform.com/help/546-How-to-Set-a-Field-as-Required-or-Non-Required

Please let us know the form with which you are having this issue with, and we will take a look. If you have embedded your form in any web page, please share the web page URL as well, and we will take a look.

We will wait for your response.

Sorry for the incomplete question. Yes, you got it right. Is there any setting that we can change to avoid this? Thank you
