As I have said before, I invoice and receive payments on an industry specific site and then download to QBO every morning.  When I look at my Invoices and Received Payments report, there are multiple invoices for each customer on the chosen date.  These are exact duplicates.  If I modify one of them, the modification does not apply to another.  On average there are 2 per customer.  Can anyone explain what is happening, how I fix it, and how I avoid it in the future?  I have included a portion of the report to give you an idea of what I mean.  Thank you.
