Accrual plan balance deducting incorrect dates

Hi All,

We've noticed an issue with our absence accrual balances calculating incorrectly. For example, employees who have booked half days and it displays correctly in their booked absences section, but in the balance section it's deducting a full day when looking under details. It is also deducting bank holidays in the balance section although the calendar events are set up correctly and in the absence booking section, it's not showing the bank holiday as a deduction from annual leave.

Does anyone come across this or know what could be causing the error?
