Problem 1 (See picture): The text is missing on the link. Only the picture is there. I think the text should be "Performance Report"

Problem 2 (See picture): The performance report picture is missing for each test on each job. If I try to open the picture I get this error.

Caused by: java.lang.Error: Unresolved compilation problem:
