How to reproduce

1. Go to Xray → Reports → Test Runs List.
2. Click Columns and add extra fields (e.g., Labels, Parent, Assignee, Revision, Test Plan, Iterations, etc).
3. Confirm that the additional columns are visible in the Jira report view.
4. Click Export.
5. Open the exported file in CSV/Excel.

Actual result/Attachments
