Reports that worked at the end of February no longer work. Since then Recorder has been upgraded to latest version, with latest dictionaries installed.
The problem has been identified that it is no longer possible to produce a Taxon report via the reporting Wizard, that selects particular super families - i.e. to produce a report of all Butterfly species from the Lepidoptera.
The resulting report just returns zero records.

Producing a report of all Lepidoptera works, returning the expected records.
