Recurring Invoices Duplicates after v16.0

Some users are reporting that recurring invoices are generating multiple invoices after the latest update to v16. The likely cause is that the recurring invoice was missing a n invoice before the latest invoice generation and Sprout Invoices tried to resolve it by making another. Let me explain with an example:

In the example above you see that two invoices were generated on November 5th. However, the start date for the recurring invoices in July 5th and there wasn't an invoice generated on that date. 

The result: the first invoice generated on November 5th was to reconcile the missing invoice for July 5th (since one wasn't generated on the start date).

This was intentional fix for v16, since users were pointing out that the were missing some generated invoices. However, some users are pointing out that they simply ignored the bug and didn't expect the missing invoice to be generated. If you're one of these users I sincerely apologize for not considering this condition with the release, hopefully I can help with steps to resolve your situation below:

Recommended Resolution

1. Void one of the newly generated invoices.
   1. Do not delete the invoice, unless you adjust the start date (in this example, it should be reset to 2017-08-05). Otherwise Sprout Invoices will determine there's a missing invoice again.
2. Confirm the next generation date is accurate.
   1. If it is not please contact support with a screenshot of your recurring invoice configuration.

If you're using Sprout Billings

You will may need to process some refunds if both invoices received automatic payments on the generation date.

1. Void one of the invoices (same as above).
2. Manually void the payment associated with the voided invoice.
3. Manually process a refund at your payment processor.
