Hello,
It is intended that Safari be fully supported in regards to the Cloud configuration portal. There was a recent update to the portal where clearing the cache may be necessary to prevent seeing the two search scope buttons.
- Click Safari in the upper left hand side of your screen. In the menu that appears, click Preferences.
- In the window that appears, click the Privacy tab. Click the button Remove All Website Data....
- Click Remove Now in the pop up window that appears.
If this does not help, I would recommend you open a case with the Cloud support team to investigate further.
