Maybe you should be able to add chapters with out adding a draft.
Hope you do it!
Your draft is a 'chapter' waiting to be voted on. In order for your specific 'draft' to become a 'chapter', it has to be submitted, then voted on. If your draft doesn't get the amount of votes to win (so to speak), it just remains a draft. If your draft gets enough votes, and wins, THEN it becomes a CHAPTER, and remains a permanent part of the story.
Hope this helps.
