3 clicks = 0.00 cents? and an non-zero eCPM?

I see this in my stats for a channel

I've been using adsense for over 2 years now, and havent seen this before. I have 3 clicks today in a channel for 0 cents in earnings. AND, there is a non-zero value in the eCpm column. Did my clicks only get fractions of a cent which dont add up to 0?

Thanks

It happens in the start of the day when stats are not updated. I have seen zero clicks and a couple of cents. Wait till the end of day
