email notifications for agent-created tickets

[gears]

previously before changing old 3.0 notifications to invalid and using new 5.0 notifications, if any agent created a phone or email ticket through the web interface, all agents would receive an email notification which is the desired result

currently:
agent1 creates phone ticket with agent2 assigned as the owner >> only agent2 receives an email notification, no other agents receive the notification
agent1 creates phone ticket assigned to Admin OTRS (root@localhost) >> no agent receives notifications
agent1 creates phone ticket with himself assigned as owner >> no agent receives notification

All agents do still receive email notifications for tickets created by customers for the queues the agent has selected in their preferences. All agents who should receive the notification have all the queues selected in AgentPreferences My Queues with all the notification options checked. Also tried adding "TicketCreate" as the event which is what was set on our legacy notifications but still didn't get email notifications for tickets agents create and the notifications for tickets customers created then arrived twice per ticket. Is there a way to restore the original agent ticket notification behavior? Thanks for any ideas

Current notification -
name: Ticket create notification
event: "NotificationNewticket"
ticket filter - empty
dynamic fields - empty
article filter - empty
recipients - All agents subscribed to the ticket's queue + All agents subscribed to the ticket's service
enable this notification method: Email
active by default in agent preferences: checked
notification article type: email-notification-ext
email template: default

i use Additional recipient email addresses under Notification Method for this.
And added the emailaddresses separated by a semicolon ;

we also have several agents but they are using one single email address for customer issues.

it's a good idea but I think that will result in duplicate notification on tickets customers create since those notifications are still making it to agents who subscribed to the queues. we could get away from using the my queue subscriptions for notifications and go back to explicitly selecting queues + agents to receive notifications in the notifications options but that might be a step backwards


EDIT: revision to the current behavior -
OK: agent1 creates phone ticket with agent2 assigned as the owner >> only agent2 receives an email notification, no other agents receive the notification
OK: agent1 creates phone ticket with himself assigned as owner >> all agents with the queue selected in their my queues excluding agent1 receive the notification
Not OK: agent1 creates new phone ticket with no owner (Admin OTRS root@localhost) >> no agent receives notifications

So the question is how can notifications be emailed to agents with the ticket's queue selected in their my queues for new agent-created tickets with no owner (Admin OTRS root@localhost) set?
