Events disappear when I expand the date range
When I view my events for teen registrations (with a secondary dimension of source/medium) for July 18-19, you can see that several sources referred these events, including bing and duckduckgo.com:
When I expand my date range from July 18-19 to July 1-19, a lot of the sources are missing:
(These two rows are the only results).
It makes sense to me that organic google & direct increased when I expanded my date range, but what happened to sources like cnn and duckduckgo? Didn't they refer events on July 18-19? Why would they not show up if I look at July 1-19?
Any insight anyone has would be much appreciated.
