When clicking the looking glas feature for any cell in the "No grouping" row you are taken to the Integrality tool from which you can trigger two queries (e.g. https://tools.wmflabs.org/integraality/queries?page=User:Lokal_Profil/BBR_dashboard&property=&grouping= ).
This feature is broken in two ways.
The first is that the property does get passed on to the tool. This is because it does not get written to the template at all for cells in this row.
The second is that the generated queries cannot handle the case where there is no grouping qid.
