Go to:
  1. Fundraising > TeamRaiser
  2. Manage the specific event
  3. Choose the Delayed Self-Pledge tab
In this area there are options to Process all outstanding delayed self pledges or choose a set of specific gifts and process only those.  

Do NOT use the Process all button at the very top of the page.

Instead, choose specific gifts by marking the checkbox beside them.
Once you have selected the ones you want, click the Process selected pledge button just above the list.

If you have many gifts to process, you can choose a page of gifts at a time by marking the checkbox in the header row. If you have any other questions, please refer to our Delayed Self-Pledge Help Documentation.
