The assessment forms in the Workshop have two parts. The first part is controlled by the selected grading strategy method and typically consists of multiple criteria of the assessment. The second part is so called "Overall feedback" field that is appended below the assessment criteria.
In these screenshots, you have not configured the assessment criteria. So the assessment form (its first part) is empty and the latter screenshot shows nothing in the "Assessment form" collapsible section. That is also why the workshop can't calculate any grades out from these assessments, it has no data to work with. The only thing it has is the "Overall feedback" conclusion.
