Are you talking about the ignore mismatch feature on the device's audit page, or the controller overrides on the device's manage page?
If it's the ignores, click the "Customize" button on the device's audit page, then unselect any checked boxes next to the rows and click "Save".
The controller overrides on the other hand are a legitimate way to resolve mismatches. The most common use case for overrides is to make Airwave not desire to delete unreferenced (i.e. unused) profiles from the controller.
