Bug Description
When aggregating a field, groups alphabetically prior to a group where the values for the field are all NULL will not render.
In this example, denials in GroupA is always amount=NULL and the categories aaa, charges do not render for that group. Everything works fine for GroupB presumably because denials has at least one non-NULL entry.
