Slave ticket receives quote email notification from master ticket

[drodralv]

Hello!

Whenever a ticket is already linked as slave to a master, since then, when a notification sent in the master ticket, that notification is sent to the customer user of the slave ticket, even if the notification is set as internal email, both int or ext are also sent to the user of the slave ticket.

Is that normal? Agents are claiming that is not, user for slave shouldnt receive notifications from themaster notifications which are internal, just sent to a role group to review the master ticket.

Thank you

Something to add, using email outbound does not happen. I see that the difference is that event notifications are "system" and the email outbound are "agent"
