Context:

See screenshot: The frontend requires all entries in the result map of a report to have the same result keys, even if there are no instances in the respective bucket.
In the screenshot attached of a groupBy instance date - distrBy date variable  report, the instance date bucket 1970-01-24 has an empty value because there are no instances for this date. However, it should have the same distributed by entries as the bucket for 1970-01-25, each with a 0 value.

AT:

• In the result map, all distrBy date result entry keys are present under each groupBy parent bucket even if there are no instances in the respective groupBy entry
