FitDay giving me problems

I recently started using a FitDay journal and I don't know what's going on but it seems totally off.

For the last two days I ate the exact same menu and exercised the exactly same way for the same time.

But it's telling me that Friday's Calorie Burn Total was 3576.
And it says yesterday's Calorie Burn Total was 2181.

I don't get it. Is it just me?

Nevermind...figured it out. For whatever reason it didn't retain my original weight when I signed up. So who knows what weight it was using to calculate my information.
