Statistics last 30 days


The google box "Statistics last 30 days" in WP post view, is very confusing.. Look at attached print screen. Its tracking pageviews good, but its very low amount of tracked visitors/visits.
Its the same problem on all our posts. Do you know what can cause this? When I sign in directly on Analytics we got about 1.8 pageviews per visit all over site.

Best regards,
