Holiday leave and sick leave accrual

Hi,

When I put base hour for one particulary employee, there is no holiday leave and sick leave accruing. When I try to do payslip to others, they all have holiday leave and sick leave. Only this particulary employee have 0 hour when I insert based hours in this employee palyslip.

I have checked card list, all employees holiday leave and sick leave are based on gross hours. 

Why this particular employee don't have? And how can I fix it?

Regards,

Lydia
