Reading List in Safari in Feedback Posted February 22, 2014 It's also good to note that there's a 'hidden' toggle on the Mac version of Safari for Reading List. On the reading list sidebar, be sure to scroll all the way to the top. Above the topmost article is a hidden search bar and button toggle. My guess would be that your toggle is set to 'Unread' instead of 'All'. Once you open an item from Reading List, it's marked as 'Read' and if you're only seeing the 'Unread' items, it'll look like it disappears from there. See the picture below for a better explanation. I'm not very familiar with Reading List on iOS so I can't give much help there. Hopefully this fixes your issue.
