report

I need to understand the two blank columns that are on the report that when deleted wipe out the entire results. Why are these columns on the report? I am having to provide Verizon a report that is in a .csv format and remove a few of the columns you created for the original report for the internal report and when I try to remove the blank columns a and c it removes all the data in the report. I need to be able to remove these to save this in the same format for their program to pull into their BI tool. Can you explain the reasoning?
