It appears you have adjusted your baseline metabolism to something really low, probably 0, which is adjusting the activity calculations accordingly.
To fix your baseline metabolism:
Click the "Customize" link next to "Lifestyle" in the activity log (it's in the screenshot you uploaded) and change your baseline metabolism back to one of the preset equations.
After you have done this go back to your activity log. If the numbers are still off delete the activities and add them to your log again.
I tested all of these steps and this should make everything work again. Please PM me or post back here if you have any troubles.
