traceability report does not show test runs and defects for parent requirements

The Traceability Report does not show test runs and defects for parent requirements.

If you have an Epic with a Story, and the story is being covered by one Test for which you have one or more runs, if you list the story and the epic issue in the traceability report, it will show incomplete details.

While the Story shows all related runs and defects, the Epic does not show neither test rund nor defects

How to reproduce:

• create Epic
• create user story for the previous Epic
• create a Test from the user story screen
• from the Test, create a Test Execution and run the Test
• create a defect from the execution screen
• go to the Traceability Report and filter for the story and for the epic issue; the epic shows incomplete details
