At the local level (my computer) I have entered two kinds of records: Composition and Critical Reading. If I try to filter by Composition the PERIOD Results page gives me both kinds of records. The same happens if I try to filter by Critical Reading. The Period Results page ALWAYS gives me ALL the records. The PERIOD Results page does not filter records at all. It always gives ALL the records.
Update: The DAILY Results page gives the desired results. The DAILY Results page works well. The PERIOD Results page does not.
