Weird, my KControl.desktop files does have this third category but they still 

According to the spec [1] "Core" is one of the registered Categories.

Can you check if it makes a difference when you reorder the three list items?
(e.g. Qt;Core;KDE)

Do any of the .desktop files installed in /usr/share/applications 
contain "Core" or "Settings"?

No, that shouldn't be the cause.
The KControl.desktop file from our repository [2] contains the "Core" part and 
I am pretty sure this would have been removed if it weren't supported.
