Vacation accruals aren't processing for all off-cycle hours.

Our vacation accruals are run on a biweekly basis for some groups. We have noticed that they calculate for the on-cycle pay, however for some employee's that have off-cycles, their hours aren't included in the vacation accruals that are run after the pay.

Even now going back, we aren't able to run accruals for the periods that have the off-cycle hours.
