This is the new Miscellaneous category. Publish the posts you want in here. I've edited the Miscellaneous promo on the home page to link to here.
If you don't want it to be called Miscellaneous, rename it (and change the slug), or just delete it and create a new category with the right name. You then need to edit the Miscellaneous promo as well, to give that the new name and change the redirect link.
