Sync bar not triggered

Is there a way to explain why the workflow in the image below stops after the action AVIS_DIRECTEUR?

Each action is an approval, if any participant refuses the request all pending actions are canceled and the workflow continues (RAISEEXCEPTION at the bottom).
But in this case, if AVIS_MEDICAL is completed first the workflow works as intended with AVIS_COMEX and AVIS_PRESIDENT following AVIS_DIRECTEUR.
When AVIS_DIRECTEUR is completed first, nothing happens.

Hi @ehoffmann,

I recommend opening a Helpdesk ticket so that the team can investigate the issue.
The information provided is not sufficient to identify the source of the problem.
