Respond by worksheet creates a single CSV file not multiple worksheet

Summary:

According to standard instructions in the manual, the file created at the functionality Respond by Spreadsheet would be created in the format based on the style. In the Negotiation style I only select Lines and not requirements.

I obtain a CSV format that contains comma separated fields enclosed in quotes. See second Image.
I do not obtain multiple sheets inside the spreadsheet. How can I achieve this?

Are there any modifications to Fusion Setup and maintenance or Excel that needs to be done?

What CSV format is exported and what format is required for import?
