Why does Satellite's Manifest Refresh task remain pending even though it is 100%?

Issue

Manifest refresh stuck at 100% :

"Refresh Manifest 100% Complete"

There are no running or paused tasks.
The Satellite service already restarted with satellite-maintain service restart.
The Satellite server has been also rebooted.
