Cluster services duplicated on Services tab

Cluster services (e.g. Hive, HDFS ...) are duplicated on the "Service" page of "Operations" group (see attached services_view.png). On a "Dashboard" page the number of monitored services is correct (see attached dashboard_view.png).

I'm using Chrome 58.0.3029.96 (64-bit) and running Kylo Sandbox 0.8.0.1.
