I figured it out- the client had told me they hadn't touched the transactions, but they had indeed reversed them a while back. When they ran the reconciliation report from before the reversal date, they were showing as outstanding, but obviously they weren't available to clear since they had since been reversed.

My mistake was assuming they were correct when they said they hadn't touched the transactions!

Thanks!
