Why are accrued hours not appearing?
Have you posted the accruals in Admin > Accruals? Additionally, you can schedule automated accrual postings in the Accrual plan itself. Note that you must also schedule the accrual to occur in Admin > Schedule.
If the Leave report is not showing up in Quick Reports - Leave Balance, confirm the leave project(s) are identified as Designate as Leave Project on the Project Profile Time tab.
