Close or delete it. After noticing and seeing that some of my stories has 'adwalled', that produced the correct term for what I needed to search and that resulted in https://forum.novelupdates.com/threads/how-do-i-see-adwalled-releases.71354/ and https://www.novelupdates.com/nu-policy/ This is not possible, and I'll just resort to adding notes than (still wish that if they are notes, it's highlighted or show some color to indicate they is a note on it).
From what I understand novelupdates only lists visible chapters as soon as they go behind a pay wall it is treated the same as if tHe chapters were taken off the site
