The One Name Studies page is just a normal category. It has two lists. There's a full list of categories, which isn't paged, and then a list of free-space pages, in chunks of 200.
Your category is in the first list. You don't have to have any space pages.
As for what you have to do to get rid of "Nobody has started a Lockhart project yet", I only wish I knew, I can't get rid of mine either.
