Blog Post Showing Up Twice

I use Google Drive to sync to my blog. I added a file to the folder, then moved it to a tagged folder, and now the post is showing up twice on my blog, despite having deleted any duplicate files and reloading my Drive and my blog. The “Fix Your Folder” option is not working, and the post is showing up twice in my Archives as well. Also, as an aside, old tags that I have removed from posts are still showing up in my Archives.

Help!
