This behavior can be changed by modifying this setting:
- Go to Fundraising > TeamRaiser.
- Find the desired event and clicked the Modify link.
- Go to step 3, Select Event Options.
- Go to step a, Define Fundraising Options.
- Uncheck the check box "Yes, credit the full value of recurring gifts immediately."
With this box checked and one submits a sustaining gift the value of the entire pledge will be immediately included in the participant's fundraising totals. However, as the sustaining gifts process, this value will decrease by the amount of the submitted gift displaying that of the initial (or "seed" gift) + the remaining balance of the pledge.
