This may be happening because your acknowledgement process acknowledges the patron on the transaction and the recognition recipient.  For this reason it may appear that multiple acknowledgement letters are being generated for the same transactions. Follow the steps below to remove recognition recipients from your acknowledgement process:
  1. Click Marketing and Communications > Acknowledgements
  2. Click Edit next to processing options
  3. Un-mark include recognition recipients, as you see below
  4. Click Save
    • Note: This issue could also occur if you don't filter your acknowledgement selection on transactions with an application of sales order.
