Drafts going to wrong folder

For some reason I have two draft folders and two in boxes under my primary email account, one as a folder directly under the account, and one as a sub-folder under the “more” folder.  My drafts are going into the draft sub-folder in the “more” folder.  How can I get my drafts to go into the primary draft folder, and then get rid of the unnecessary inbox and draft sub-folders in the “more” sub-folder?
