Calorie guide changes??

I noticed this morning when I clicked one of my "tagged" items, Espresso, that it showed up as 2 calories, instead of 9 and last week, my egg white started showing up as 16 calories instead of 17.  I didn't think much about the egg white, figuring that perhaps CC had updated their database.  But, there's no way that Espresso went from 9 calories to 2.

Has something changed, or has anyone else noticed things not matching up to what they were a few weeks ago?

Just curious

Celery went from 17-19 cals a cup... not much, but interesting.
