Issue View Tabs disappear when issue is closed

[steven.allcock]

We have created an issue tab on our incidents and when we close an incident the tab vanishes, but if we edit the issue it reappears.

is this something thats by design or a setting we are missing

Please check if the Tab is only on the Edit Screen of the issue Type or it is on the View Screen as well. As Closed Issues are often configured to a "view only" state.
