Even if you have corrected the underlying cause, error messages on the scrub only go away if you do one of two things, either:
- Re-upload the census, or
- Click the link on the scrub results screen to clear all participant errors/overrides
Either way you'll need to re-run the scrub, but doing one of the above will clear the error messages. They will only re-appear when you re-run the scrub if the underlying cause has not been corrected.
