[Test Runs List] Not all columns are exported to Excel

When exporting the Test Runs List from Jira  to Excel, not all columns visible in the Jira report view are included in the exported file. Some columns appear in the UI but are missing in the export.

Steps to Reproduce:

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

Expected Result:
The exported Excel file should include all columns visible in the report view, matching the on-screen layout.

Actual Result:
The exported Excel file contains only some of the columns; certain fields visible in the Jira UI (e.g., Labels, Iterations, Links, etc.) are missing.
