GW calendar publishing host shows - not allowed - entries in search list

GW24.3

Hello,

in GW-Admin I disabled "System | Calendar Publishing host | allow publishing calendars in search list".

But browsing to http://MyDomain/gwcal/calendar some entrys are showed in the list.

All calendars I published in the last months aren't shown, that's fine.

But calendars that were published first time about 10 years ago remain in the list until I switch off the whole calendar publishing for this person in gw-client.

Any ideas?

Thanks,

Holger
