Hi @Eddy Dickens,
you can change the default template when you go Email this issue configuration and then to Contexts.
Choose there the context that applies to your project. There you have to option to choose another default-template (Content-Section > Template)
If there is no template you want to use, you must create it in the "Emails Templates" in the menu on the left first.
