If you are seeing three Opportunities created when an initial recurring donation is process:
- A "Closed Won" Opportunity dated on the date of the transaction
- A "Pledged" Opportunity, data on the date of the transaction
- A "Pledged" Opportunity, dated on the dame date of the following month of the transaction
If this is the case, and you have recently updated to Enhanced Recurring Donations, then it's likely a parameter in your NPSP settings.
If you look in your NPSP settings, you will likely see that a new parameter, "Installment Opportunity Auto-Creation" may be set to: "Always Create Next Installment".
Set that to, "Disable First Installment on Create" and that should resolve this very specific issue.
