MYOB Payroll adds 38 hours to standard pay

Hi,

I've been using MYOB payroll for several years now and every time I add a new employee I set the standard pay hours to 0.  MYOB payroll will then set this back to 38 in the payroll run and then add this to their clocked on hours meaning that an employee who works 10 hours gets paid for 48.  I ensure I double check every employee I add to ensure their standard hours are set to 0 bit it still happens every time.  I use Tanda for timesheets and rosters and I have seen this problem in other forums but no resolutions.  This is costing me thousands of dollars a year and seems to be a MYOB payroll issue for several years now given the number of posts regarding this.  Please advise on any current resolutions or work in progress.

Thanks in advance.
