Run two background processes in parallel, triggered from Orchestrator

Hi guys,

I am testing the running of parallel of two background processes, from Orchestrator. I have two different background processes, with a 30 sec delay and a log message activity.
Running them from the Agent is no problem, they run in parallel, and I can also see both of them running in parallel in Orchestrator, after I start them from the Agent.
But when I start the run from Orchestrator via the Run Process button, the second one waits in pending mode for the first to finish. So they do not run in parallel. Any idea why ?

I am using the community cloud Orchestrator.

Thank you,
Gabi.
