Symptoms

In 13c EM Console setup, repeating blackout has been created for multiple cluster targets across different hosts.
Though the blackout has ended successfully, some of the targets are still stuck in the Blackout status.
Verifying the target availability dump of one of the target (collected via the EM Diagkit command: repvfy dump availability -name "<target name>" -type <target_type>) shows:

Above data shows that this particular target is in Blackout though there is no active blackout window.

This is affecting the monitoring of these targets.
