Delete a new incident template, Can't

Delete a new incident template, Can't

Hello

We had a service category request and we have it disabled now. I also deleted all tickets created using the template.

The issue I am facing now is under new incident tab [we changed the display to new ticket] there is a menu that I can't get rid of. 

Please check the attachment. How can I get rid of the one that is under ITG menu?

Thank you
