The status for this title should be changed to released, since it got released a month ago worldwide. I don't get why this hasn't been done automatically since every added released date for the title had passed by now.
This sounds like you are using the old (7+ years out of date) version of IMDb.
Please go to your site settings at https://secure.imdb.com/register-imdb/siteprefs and ensure both "Always display full cast and crew credits" and "Show reference view (old title/name page layout)" are unchecked. These options are only for people who do not want to use IMDb's latest design and features; they are unsupported and are full of bugs so are not recommended for general use.
