[9.000-8] Can´t any do in Profiles

Hi,
i create a backup on running 8.305 and install new v9 as software-image. After import the backup-file, all seems cool.
Now i would do anything in the Webprotection with profiles and exception, but in cant. It is not possible to change, delete or add (:eek:) in the profiles and exception. Following errors:

By deleting profiles:
The web filtering profile object 'Game-Computers' is required by the HTTP/S proxy profile list.

By adding profiles:
The http->defaultblockaction configuration needs web filtering objects.

By changing profiles:
The http->defaultblockaction configuration needs web filtering objects.

By change or delete exeptions:
The web filtering exception object 'Antivir-Updates' is required by the http->exceptions configuration.

Some same problem or known import-bug?
