Fix Duplicate Answer Labels

The metadata transformation will validate if any answers are duplicated within a question.  Note the behavior is different when you made changes:

If you didn't touch the answer block at all, Forsta Visualizations will accept the duplicate and add a suffix to the label {nr}.So if you import question Country:

1: Sweden

2: Germany

3: Sweden

This will be accepted and imported as:

1: Sweden {1}

2: Germany

3: Sweden {2}

However, once you touch this answer group and adjust a label, this it will not add any suffix, and it will be blocked because of this duplicate. For example, you are adding an answer Belgium:

1: Sweden

2: Germany

3: Sweden

4: Belgium

You use the MDT to adjust this label for Belgium because it was cut off, so it becomes:

1: Sweden

2: Germany

3: Sweden

4: Belgium

And now Forsta Visualizations will not add the suffix anymore, and your import will throw an error because Sweden is in there twice.
