You created (3m56s) matching zm-9Y7XE9wo (3m56s). Something went wrong, the file has no thumbnail, that's why you get only a gray rectangle instead of a thumb, and of course the name is wrong, it should be Just Dance 2018 - Luciano Spinelli - All You Gotta Do. Just add the same video again on w:c:justdance:Special:WikiaVideoAdd, and ignore any warning about the duplicate.
