How often the report on leave balance update?

Hi there,

I was trying out on{businessid}/report/leavebalances, but it seems the value of “accruedAmountInDays” is not updated after some of the leaves are used. I am wondering if the “accruedAmountInDays” value is not meant to be deducted by the same amount after leaves are used? If it does, wondering how often this field is updated?
