Yes, I have been having an issue in the Campaigns screen for months now. When I go to Acquisition > Campaigns the results display rows 1-10 by default and my total sessions is 421. However, when I change the rows to 25, the total number of sessions changes to 210. Also, each campaign line has a number and it changes as well.
You can see my screen shots here:
ROWS 1-10

ROWS 1-12

Just wondering if anyone else is see this as well? You can view the help thread here: https://groups.google.com/a/googleproductforums.com/d/msgid/analytics/dea4e899-7384-4b0f-a4e0-a380e9b40c6d%40googleproductforums.com
