Possible duplicate payments

The same invoice from the same vendor, for the same amount, paid more than once.

Duplicate payments are the most common error auditors find in payment registers.

How this is worked out, and what it cannot tell you

The Open Contracting Partnership's guide to red flags puts it this way: a red flag is not evidence that anything wrong happened. It points at something that may be worth a closer look.
