How do I eliminate categories from a past version of a form?

Hi, when I export my form submissions into an excel sheet, there are four extra columns that are empty due to an "Address 2, city, country, and state" not being on the form anymore. How do I fix the form to where those columns do not show up without getting rid of past submissions that had the indicated fields?

You may generate an Excel report, there you can uncheck those fields which you don't want to export.
