No macOS Updates shown in AppStore

Hi,
since High Sierra I dont get any new macOS Updates shown in AppStore, but anything else such as XCode, iTunes etc .

Any idea what could be wrong ?

after the high sioerra update some preferences seams to be changed :

After re-enabling "install system data files and security updates" them I got instantly new updates shown , yeah.
