I have created plan from the project, which has issue types epic, story, task, sub-task. In the plan the task issue type is not displayed under the epic where it was created. I do not filter issue types, nothing is excluded.
When I choose the hierarchy from epic to sub-taks, tasks are excluded from the view. Stories are under the epics correctly.
How do I get task issue types to be be displayed under the parent on the plan.
