The Sales Order had 2 Invoices connected to it as there was an installation charged from it first and then the materials were charged 30 days later.  The report shows the Sales Order and each Invoice and it says "Invoiced in Full" on it.  However, it still shows as open in the Open Sales Order by Customer Report.  The icon on the Sales Order to "Mark as Closed" is checked and greyed so that I cannot click on it.
