Try each of the following steps in order until the issue is resolved:

  1. Select gift sub-filters for the Summary Information filters rather than selecting them directly on the Criteria tab of the query.
  2. On the Output tab, remove any Summary Information fields and reselect them from the Query Fields folder, ensuring they have the same sub-filters selected in step 1.
  3. Go to Tools, Query Options, Gift Processing and select Donor or Both.
