I have an advanced roadmap plan that is using a JIRA issue filter to determine the scope of the plan. The Filter returns 27 issues but in advanced roadmaps it's only showing 25 Issues in the plan.

The missing issues are sub-tasks that have been moved from Resolve to Closed.
The Roadmap has no exclusion rules added, so these should not be excluded.

Looking at the missing issues in JIRA, they do not have the 'green-tick' that shows on completed subtasks - this is the only thing I can see that might be triggering the issues to drop from the Plan.

Any ideas on how I can re-add these to the plan and keep them visible?
