Discrepancies in the downloads values

I have noticed that there are discrepancies between the downloads values presented in the files section of the product and the value displayed in the Payout. I give you an example …
In the wallpaper “Plasm inGreen” the value of downloads presented (at 01 May) in the files section is 70, the value presented in the Payout section (referring to 30 of May) is 48,and the estimated value of downloads on today’s date is 5. So, as you can see, it doesn’t seem right.
