This likely occurred in the process of updating/importing data. Wait 10 minutes to see if it changes. If it does not change, revisit the issue after the next data import which occurs mid-morning and early afternoon.
An alternative explanation may be that the waiver status was updated between processes. The next import should correct the issue unless the pay period has ended. In this case, the changes should have happened earlier before the end of the pay period.
Waivers apply retroactively, so any change in a future pay period will also affect previous pay periods. Staff should always retain copies of waivers once they’re filled out in order to have proof for historical purposes.
