Events breakdown does not match total events
When you go to Google Analytics reporting, navigate to Behavior - Events - Top Events, and break down event counts by a dimension, then the sum of the counts in the breakdown does not add up to the total number. For example, here the report contain 1154 events, but its breakdown only adds up to 138:
Why is the total not equal to the sum of the breakdown?
Re: Events breakdown does not match total events
It seems there are events with missing event action, since the dashboard displays the warning 'This report has been filtered to include only data where there are values for "Event Action" dimension.' (see also this article). I'll check the event logging code.
