Hmmm, understand and might make sense if maybe selected an item from menu and product during the day after one had been sold perhaps but that would be unlikely on multiple occasions as this has happened and also when looking back the report shows correct group breakdown would suggest against that type of issue and more to a time/printing issue.
Will upgrade a backup on the bench and run some tests.
We will probably just upgrade the site to v5 anyway but was a weird one I wanted to ask about.
