Information not showing...

I tried asking this yesterday on the Tech forum but I didn't get a response.
This past week I had one day very out of the ordinary. Long story short I went on a very long hike, which turned into an excessively long hike because we got lost. Basically I burned and consumed MUCH more than my usual amount, and my deficit for the day was in the negative. Now that day will not show up in my weekly chart. I was hoping to factor it into my overall week information. Any idea why this day shows up blank when I try to see my weekly info?
