Trying to figure out SMP report

Hi,

 

I just downloaded my first Selling Manager Pro csv report so I could look at my sales figures from a few months ago.

 

Next to the column called "Gross Sales", it has an additional 2 columns called "Cost" and "Gain".

It has inserted random figures in these colums - almost as if it has taken upon itself an attempt to work out how much my items cost me to produce and then what my profit is from the sale.

 

It cannot possibly know that information, so what on earth is that all about?
