A pleasant day, LINKConstruction.

Let's go over and resolve your concern about duplicate split transactions from your Profit and Loss report.

There is a possibility that the invoice was manually received payment reason why it's showing as paid in the Profit and Loss report. In order to fix this, let's open the invoice and remove the Receive payment transaction associated with it.

Here's how:

1. Go to Sales then All Sales.
2. Locate the paid invoice and click it.
3. From the invoice screen, click the link for payment made.
4. Click the link under Date. This will route you to the Receive payment screen.
   
5. Click More and choose Delete.
6. Choose Yes to confirm.
   

This will now change the status of your invoice.
