Enphase live data choppy

I noticed that my Enphase Auto Uploaded data has zeros populating the chart and making it appear as if the solar system inverter is flipping ON and OFF:

Not sure why this is occurring but am using the Auto Uploader Enphase function to upload data automagically:

The zeros are not real data or my lights would be flickering away and the Utility provider would be on my case about frequency degradation.

PV Output please advise if this is a known bug or I need to investigate my gateway data upload settings?

Thanks!

well it says on your screen shot smallest poll time is 20 min you are are 15min
