Customer Statements Glitch

Julian1961

When I open Customer Statements I have a glitch.  A customer, who is also a supplier, comes up with a balance owing of $786.50 which is actually an amount for a bill that was paid on October 28, 2016! There is no amount in the overdue column, which there shouldn't be because it's an amount paid not receivable anyway.  Is there any way of deleting this entry from Customer Statements please?
