Bug in Orchestrator Logging?

Hi

I’m testing the scheduling functionality of Orchestrator with some very simple processes.
One gets a file from a folder and tries to add it to a queue.
The other one just waits a couple of minutes.

When I look at the logging of the robot in Orchestrator, I see that from time to time logs are logged twice or more.
E.g.

Is this “normal” behaviour?
What causes this behaviour?
Is this a bug?
