We're seeing a concerning trend with rerun checks. I'm hoping that I didn't miss a change to Check 21 rules.

We return checks to the BOFD as NSF. The BOFD reruns the check a few days later (all normal so far). The thing is, the BOFD's are re-running the original check, not the Check 21 image that was created when they took it for deposit initially. So - the rerun check we get appears to be a duplicate item instead of a re-deposited item.

We're seeing this from a wide variety of banks, big and small. Anybody come across this? Did I miss something? We're planning to return those 'original' checks as duplicate items right now.
