Whoops!
You have specified movies that have not yet been added to iCheckMovies. The missing movies have automatically been added to the movie import queue. You will automatically receive a notificaton when the movies have been imported, if you have specified so in your notification settings.
Go this message when trying to import a movie that I had just added, https://www.icheckmovies.com/movies/kazetachi+no+gogo/
Since posting this I have been able to add the film to my list successfully.
It takes some time before you can add a newly added title to a list. Although the import is ready and you can check a movie, adding it to a list doesn’t work instantaneously.

The titles that get added to the import queue automatically while creating a list will automatically be checked once imported. I noticed by accident that I had four checks from last week, that I didn’t know about. These were imports from a newly created list. I never had the option to select whether or not the imported titles should be checked.
Are you sure that’s still true? It was a bug last week, but I think it was fixed.
Edit: yup still true, but only when added through a list, not if added to the import queue manually.
