When changing result views or pages in a result view, "Current Stream statistics will be cleard on port: XX" message appears and Results counters (Stream Block Results) are cleared.
UI.log shows all ports receiving same message:

Also, sometimes GUI applies automatically even though there is no change in the configuration and results.
