Sick Leave Entitlement in MYOB AccountRight

I am setting up a new employee on MYOB AccountRight.  My query is about Sick Leave Entitlement.  My understanding (Fair Work Ombudsman) is that a Full-Time employee has 10 days of SL available to them per annum.  The employee works 7.5 hour days.  That is 75 hours per annum.  The employee is paid Monthly.  Therefore each monthly pay period accrues 6.25 hours (75hrs/12mths).  Yet AR allows only 5 hours per pay period which is 8 days SL annually (8 dys X 7.5 hrs/12mths). Am I missing something here???  The Annual Leave (AL) calculations by AR are perfect, just the SL issue bothers me.
