Open iteration reports & completed, unstarted, and in-progress issues

How to Use GitLab

The docs read:

Open iteration reports show a summary of completed, unstarted, and in-progress issues.

I can only see “In progress” and “Closed” for issues during an open Iteration. If I open an issue and assign it to the Iteration, its status in the open Iteration report reads “In progress”. If I close the issue, its status in the open Iteration report reads “Closed”.

  1. Where is the “unstarted” status? How to make it appear?
  2. Is “Closed” the same as “completed”? How to make “completed” appear?
  3. In general, how does the active Iteration report determine the issue status?

Help says my version is GitLab Enterprise Edition 15.6.2-ee
