Description
If we go to the Reports page on project overview, we get $report.description instead of a description and nothing happens when we click on their titles. It is happening for all Agile reports:

• Burndown Chart
• Control Chart
• Cumulative Flow Diagram
• Epic Burndown
• Epic Report
• Release Burndown
• Sprint Report
• Velocity Chart
• Version Report

Workaround
View the Agile reports from the "Report" button on the Agile board itself (next to "Plan" and "Work" in the top right).
