I've been with adsense for many, many years and I've yet to see this happen in my dashboard.
This month I can see in my dashboard what my earnings will be for November, but November is only half over. I see my ENDING balance already, and it's not changing day to day. I see my invalid traffic for Nov as well. I should see neither of these things in the completed section, the month is not finished. My dashboard is already telling me what my final payment was for Nov 1 - Nov 30 and it's well above where I am now, it's not a running total.
