Hello! Thank you so much for the help.
I am talking about the Entries metric. We have the placement ID set to expire after visit. Could that be the issue here? I'm not sure if there's custom links. Where can we double check the campaign attribution?
Also since we are using the entries metric, how could that be double counted? I believe entries only count the first page in a user's visit ("the number of times visitors to the site first land on a given page to start their session.")
