Problem: Unable to view the applicable reporting period in the Dedup App dropdown
This is most likely due to the 'end' date defined in the datastore for the dedup 'periodSettings'. These dates use Epoch Unix Time and you must ensure that the value specified is after today's date, allowing the period to be viewed as a dropdown in the dedup app.
Please note that you will need to refresh your dedup app site in order to repopulate the values for you to choose.
