Policy Remediation
When you choose to delete or disable rules with anomalies from the analysis summary, the Policy Analyzer and Optimizer does not immediately apply those changes. The changes that you wanted to do are staged and are applied only when you click Apply Remediation.
Note that after clicking Apply Remediation once, you cannot apply remediations again based on the same report. You must run a policy analysis again on the new policy settings and remediate the anomalies using the new report.
