This request is from Ciena.
Once you mark the answer, the answer header will be saved in the answer configuration. So, if you mark the header row after configuring the answer, the response header name is not getting updated.
But when we configure Q and A first and then Mark the Header row, we face the issue: Response headers - Response 1 \ 2 \ 3... instead of the marked header rows. You can cross-check by clicking on the 'Answer Configuration' in the import file.
Whether we mark 'header rows' first or last, the client wants the header in the header row to work.
