I noticed with a recent deployment that I'm not able to delete or save the agent schedule that got created by the master agent. I don't see the issue with previous generated agent schedule instances. We're running Pega 7.4.0.
After checking sections pzRuleFormStatus & pzRuleFormToolbar, the text ( Deleted ) is shown when .pyToolBarSettings.pySave is save on the agent schedule. Also .pyToolBarSettings.pyDelete is false.
