Running tasks in upgrade menu showing 0

[Shpio]

Dear Team,
I am admin for Confluence Data Center. I upgraded to LTS bug fix patch from 7.19.7 to 7.19.11. It was a rolling upgrade. I only have 2 nodes in the cluster.

After upgrade I noticed that some number of running tasks never changed from 0.
It did not impact experience with Confluence in any way, But I could not find relevant information about it and I think is a bug which should be shared with Atlassian.
As You can see in a screenshot one node with older version had running tasks.
After upgrade both had 0 running tasks.
After 24h there are 0 running tasks displayed.

The information about number of jobs is useful for the next rolling upgrade, to upgrade one with lowest amount. But it can be replaced by simply upgrading less utilised node.

I would like to learn more about these running tasks. Do they refer to scheduled jobs ? if so then I have dozens of scheduled jobs.

'Tasks' could be coming from 'Scheduled Jobs' and also other tasks like backup or restore.

We are on Confluence 7.19.12 running on two nodes.
Both the nodes show some number of tasks running on each node.
