There are two settings that impact the full-time projected values:
Leave Accrual: Disable Projection which if set to On, only shows accrued values.
Disable 12-week accrual which if set to On, also disables projected values as well as disabling the accrual used for the calculation of rota average days.
You can see both of these settings by following the below steps:
Click Configuration then click Settings.
Expand System Settings.
Click Holidays and Leave Accrual.
