Screenshot on the example:
Scenario:
Step 1: Add a file with 5 Questions-->Import-->Response field name(One)-->Answer-->Export the project.
Step 2: Use the exported file add 2 Questions to it and re-import using update source file feature--> 7 questions gets imported where for previous 5 Questions have duplicate response field as One(original)and One(Duplicated) under each Question.
Step 3: Without removing the Duplicate response field now export the project
Step 4: Result is as in shown in the above screenshot-->The Duplicated response field answer gets updated under Question.
Discussed the issue with Ashaa who proposed in creating an S4 since this affects the process
1)when the Target file is updated without answer-->Answer becomes empty.
2)Target file with answer-->retaining the old answer
Note: The Update source file behavior also re-arranges the configuration for example if the imported file has order of 123 it changes to 321, as per Ashaa confirmation adding the information to the same S4
To have enhancement requested created as like above scenarios
