Environment (local, stage, preview, production)

Expected behavior

When a mandatory response is unchecked for a question in form builder, the form is saved. Whenever the form is edited, the previous uncheck boxes should remain unchecked.

Actual behavior

• Mandatory response is unchecked for a question in form builder.
• The form is saved.
• Form is opened to edit and a question is added. The mandatory response is also unchecked.
• The form is saved.
• Form is opened to edit, and the question with the mandatory response uncheck in the first iteration of form edits now have the mandatory response rechecked

Steps to reproduce the behavior

1. Create a form using form builder where you uncheck the Mandatory Response check box for all questions.
2. Save the form.
3. Edit the saved form by adding a question. Uncheck the mandatory response for the added question.
4. Save the form.
5. Open the form to edit and check if the mandatory response is check for the first few questions created in the first iteration.
