Custom post type ("work") – Unable to protect

Hi team!

I’m using Noisy theme (http://themeforest.net/item/noisy-responsive-theme-for-creatives/full_screen_preview/2933950) and I’m unable to protect the custom post type “work”, that is the type of *custom post* that “portfolios” are comprised of.

When I’m configuring the access levels, the “work” type of content doesn’t show up in the right column, so I can drop it into the rules (positive, negative or mixed).

How could I get that type of post protected??

Thank you very much in advance!!

Best,

Jose Miguel
