Post types no available for selection by de subscribers on the Subscribers management page.

Hello,

On the page Settings - Contents I selected all the categories, which are available for selection by de subscribers on the subscribers management page and allows them receive notification of selected post types.
But when I preview the subscribers management page, I don't see the categories.
Can you tell me how to set the categories, seeing them on the management page?

With regards,

Webteam.
