Change subject of email template in OSvC

Content

Hi,

I have a requirement to change the subject of the emails that are sent when Incident is created. As of now, the default email that is being sent is "test [Incident: 190813-000000]" which we want to change to "test [190813-000000]". I have tried to update the subject field from email template, save it and deploy it, as shown in the screenshot, but still whenever email is sent, it still sends the default subject "test [Incident: 190813-000000]". Can you please let me know how can I update it?

Thanks,

Ashish
