Server statuses are not displayed in the Gateway & Servers view of R80.x SmartConsole:
Restarting services or rebooting does not resolve the issue.
No status for VSX Cluster or VS objects although the VSX members itself are fine. Moving the mouse over the minus shows old VSX members without SIC or different version.
VSX cluster object is shown as Multi-Version Cluster after an upgrade even the upgrade finished successfully.
