This typically happens when there is a mismatch between the question's `majorqid` and its `displayorder`.

✅ How to Fix

  1. Go to the `fw_questionnairedetails` table.
  2. Ensure that the `majorqid` of each follow-up or sub-question matches the `displayorder` of its main/parent question.
  3. If the values are mismatched, the system cannot determine the correct navigation path, causing the back button to behave unexpectedly.

📌 Example Scenario

A respondent answers Question 5 and clicks Back, but is taken to Question 3 instead of 4.
✔️ On checking the database, the `majorqid` of Question 5 was incorrectly mapped to a different question’s `displayorder`.
