The reason why this headquarters receipt is being sent for the event (or purchase) is that the receipting is not setup to be sent under receipt manager.

For each object that you would like to associate a PDF receipt to in each center you will need apply this within the edit of the PDF receipt found under receipt manager.
  1. Setup
  2. Receipt Manager
  3. Search for the PDF you would like to edit
  4. Click Edit from the actions column
  5. Go to Step 3. Application List
  6. Click Configure next to the application object you would like to associate (tickets)
Once on this page you can find the object in the left column and add it individually to the right side column and save. Once this has been done all receipts going forward will be sent as the PDF associated and will associate the proper Tax-ID with the ticket or purchase receipt.
