Has anyone else noticed glitches?

I'm relatively new to cc, but whenever I add activity for the day, the calories burned by other activities goes down by random amounts. It never seems to be the same or proportionate. It kinda makes me feel like I'm eating too much when it's a balanced amount. Also, cc keeps saying I'm an 18 year old man. Not quite right.

For me, the nutritional info for my custom foods are all messed up in the iPhone app.
