can you provide the steps you take. Also, can you provide the current update you are on as well as the Enhancement dates of the programs you are using?

I have identified the problem. It all stems from speed in which the transaction is entered.
 
If you enter quickly and do not allow the "Backout Date" to populate on it's own, it will result in a bad transaction. If you understand what should be happening and you are patient, the transaction reverses normally.
 
I think there should be some safeguard to prevent this from happening.
