Try adding more content to those collections and then see if they show up.
I would - if I could. My Manually created "Kids Movies" collection has disappeared from everywhere - WebUI included.
I was able to add a single movie to a newly created "Kids Movies" Collection and It immediately appeared complete with the originally assigned Poster.
Unfortunately, the 3dot menu item "Add to Collection" is no longer available for AutoBoxSet created collections. Can you add that back please ?
