The presentation of '-' with only the assessment date in the Diagnostic results is intentional and by design in the Classic interface. In contrast, the Console interface provides an attached assessment report, accessible by clicking 'View Result' (as illustrated below).
There are no intentions to implement alterations in Classic when there is an available alternative in the Console. Therefore, we recommend utilising the Console interface to access the Diagnostic results.
FAQ: Why is there a difference in how functional skills diagnostic results are displayed between the Classic and Console interfaces?
