Zenhub Epics not displaying using the Epic template

For some reason my Epics now (was not always this way) display like a regular issue.
No table of linked issues is shown, and no ability to raise an Issue from inside the epic etc.

Silly setting somewhere, or something more odd?

Hey @JustinP

Could you send us an email at support@zenhub.com so that we can gather some additional details from you and investigate this further?
