I have epics with a set "start date" and "Due Date", below these epics I have Stories which are assigned to a sprint. The start and Due date are independent of the sprint. The managed structure is configured that the stories are grouped by Epics. My issue is that I can't see the in the Gantt chart the start and due date of the epics. This stays empty.

Would be great if anybody can help me how to be able to see the start date and due date of the Epics in the Gantt. Thank you!
