Error regarding Allowed Roles on HomePage

I created roles for my Mendix app, and deleted the default Mendix created ‘User' role. Naturally the app prompted me with errors that the user no longer exists. I deleted the demo user role, and some of the errors went away. But there are three errors, referring to the 3 home pages (Home, Tablet and Phone) with the property ‘Allowed Roles’  which I can't get rid of. I tried of course to right click on the pages to go to Properties I guess to change that but that is not an option in the right click menu. So I don't know where to go from here.
