Keyword search showing disabled categories

I disabled sounds and videos in the script. Nevertheless, they show up as a selector control in the 'keyword search' section.

How to get rid of those 2 items ?

As a matter of fact, those items also appear elsewhere f.e. in privacy settings.

Can I safely remove those modules again so they won't appear on the site again ?

Stupid question, they depend on the 'events' module, so they can't be uninstalled

No one knows how to remove those items ????
