Removing Period Totals from Transaction Details in Management Reporter

We recently upgraded to GP 2016 which required us to migrate from FRx to Management Reporter.  We are trying to run Transaction Detail reports for Department reconciliations, but some of them are now are splitting out the transactions by period with a period total row.  I can't figure out what the indicator is that is including the period totals in the report in order to remove it.  The very strange part of this is that all of the reports we are running are using the same Column Definition but not all of the reports are returning the Period Totals.

Any thoughts or advice would be very welcome.

Thanks!
