Members only Settings

I have set up settings for each download : members only, redirect: specific page. After deleting this page, the settings become: members only, redirect: inherit.

Under the download settings I put the following settings: members only redirect: to a new specific page. But instead of redirecting to a specific page I am getting only warning messages and no redirection.

I tested a few options, and find that to make the redirection work (under the download settings) I need to change members only to inherit for every post. It is a lot to do. Is there possibilities to make a bulk change for this option?

Thanks
