You can run this on the host:

    vdsClient -s 0 getAllTasksStatuses

And share the output.

You should see the status of each task - if you have a finished task,
and engine is not
clearing it, this is a bug in engine - please file a bug and attached
vdsm and engine logs.

To clear the a finished task not cleared by the engine, try to restart
the engine.

If engine is not clearing finished tasks after restart, you can clear
it yourself:

    vdsClient -s 0 clearTask <task uuid>
