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

=== ✅ How to Fix ===

  - Go to the **`fw_questionnairedetails`** table.
  - Ensure that the `majorqid` of each follow-up or sub-question matches the `displayorder` of its main/parent question.
  - 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`.
