This must be a challenging experience for you, rlwinget.
But I'm here to help check the double debit issue on your account. If these entries are the customer's payments, duplicates occur when you add downloaded transactions that you already manually entered into the program.
To avoid this from happening, you'll need to find a match for these transactions. Let me guide you on how.
Go to Banking.
Select your bank account.
In the For Review tab, click one transaction.
Select Find match.
In the Match transactions page, choose the transaction that matches and click Save.
If these duplicates are already accepted from your bank feeds, you have an option to exclude them in the Online Banking menu.
Here's how:
Go to Banking.
In the Reviewed tab, find the duplicate deposits.
Click Undo in the Action Column.
In the For Review tab, select the duplicate transactions.
In the Excluded tab, check the boxes for these duplicates.
If you're referring to something else, please provide more details about the issue by commenting below. I'll keep this post while waiting for your response.
