Appilcation is set to private any new section is default set to public cant seem to set to private

As per title, my app is set to private, i add a new section (even for the existing reports section) the following is shown

'NNNN- Internal' section is Public change (link)
Anyone can access your data and the data will also be indexed by
search engines like Google, Yahoo and others.


I click the change link nothing happens , I would expect it to go to private

Basically my app is all for internal use i need all sections private

Am using FF 3 latest

Thanks
