Wind Direction Query

I've probably done something silly, but here goes: For the last 10-12 hours it's been dead calm here. The wind direction is showing NE (which is expected as that's where the last gust came from) but the AVERAGE is showing N? I sort of expected both lines to be NE. Am I missing something?

I'm using 24 hr display, and I've enabled "use south for wind dir origin". I do NOT have "use bearing zero when calm" selected. Not sure if that helps...

The average direction takes wind speed into account, so is zero after a period of calm.
