Hi IA
Can you please provide the screen shot of the Technical Log - Fully expanded?
As mentioned by Rick, the latest ones goes to the generic user only. Your current screen shots shows two dialog steps - one started at 13:17 and after that a second one at 13:26 which went to 'CREA Usuario Generico' ... but noweher we see the user Celerino Mondragon!
If you say "after a few seconds" - then as advised by Rick, this needs to be checked in the Step History (in the technical log) for that step - what happened in the lifecycle of that step?
Regards,
Modak
