Security policy status after UCS installation After you install a .ucs (user configuration set) file that was exported from version 10.1.0 or later, the system does not automatically apply changes that you made, but did not apply, to the security policies. The system enforces the web application according to the settings of the last set active security policy. However, the system preserves any changes to the current edited security policy, and marks the security policy as modified [M] if the changes have not been applied.

but i already applied the changes before i exported them.
