This has been happening ever since we installed the plugin a year ago. In the list of posts, you can see which are scheduled (several at any given time) and the "Analytics" column shows 0 pageviews for most of them, but there are always a few where it shows thousands of pageviews and exits, etc. for posts that have never been published, but are scheduled.
Why? It seems like I can' trust that data in that column at all.
