Missing overdue invoices from open invoices reports

Did anybody else came across it?

Just ran an open invoices report and noticed a 9 months old overdue invoice on it .

Download this report monthly, covering 2 years back .

The invoice did not appear on the last 6 reports .

Went back 7 months and the invoice was there.

When I contacted MYOB support , they said that the issue was fixed, as now the invoice is picked by report and I should not be relying on one report, but should run at least two different ones  , i.e. sales ledger report to see if it reconciles.

It is very disturbing as we do rely on MYOB reports and did not realise that you need to double check such a simple report to pick up all the overdue items .  

Does everybody double check the integrity of the basic reports? Do you do it regularly?

Thank you
