Custom field 'view level' does not work

Dear all,

I added custom field ‘viewlevel’ some of my pages to make them “closed” (inaccessible) for not logged in users.

While with most pages it worked, the test revealed 3 pages that are still visible by not logged in users.

I tried to duplicate the custom field ‘viewlevel’ for those pages, but it didn’t work.

Could you please suggest a solution – how to make those page “closed” to not logged in users?
