Top 10 not complete

Installation and authentication succesful. First 2 Posts in top 10 have actual number of pageviews, but should be on place 5 and 12 (in Google Analytics live).
Other Pages and Posts have far less (unique) pageviews and don’t belong in Top 10.

On Settings page I get message
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; GoogleAnalyticsService has a deprecated constructor in …/DEVMMWB/wp-content/plugins/top-sites-url-list/ga-service.php on line 5

(Testing on local version of WP 4.9.6 on MAMP)
