Maybe it's playing after SP and Simba has another cub, or what is now very up-to-date is to take old series/movies and create alternative time lines...
But I think we should wait for a while until some new information are released, because usually this early the data it is not very reliable. And who knows, perhaps they have a logical explanation for it, which will be during the series revealed. Although I fear that it is something only for entertaining younger kids.
