Tests are shown twice in the Traceability Report if both requirements are included in the Filter for Parent-> Child requirements

Description:

Tests are shown multiple times in the Traceability Report if both the requirements are included in the Filter for Parent-> Child requirements.

Steps to reproduce:

1. Create an Epic and add a Story to it.
2. Add a Label to the Epic.
3. Add the same Label to the Story.
4. Create a Test Set and add a Test to it.
5. Add the Test Set to the Story's Test Coverage.
6. Go to the Traceability Report and filter it by that Label.
7. Generate the report.

Expected result:

There should be a traceability tree showing the Epic, the Story and the Test.

Actual result:

The traceability tree shows the Epic and the Story correctly, but the Test is displayed twice (see image below).

Notes:

• The Epic->Story parent/child relationship must be checked.
• It looks like the issue happens because the report is filtered by Label, and both requirements have the Label. As a result, the associated Test is being displayed twice.
