Sidenotes Doubling

I’m having the Doubling Issue another user described with the Implicit theme (http://themeforest.net/item/implicit-fullscreen-blazingfast-magazine-theme/8180897)

I switched themes back to a stock theme without disabling any other plugins and managed to have Side Matter work fine.

What’s odd is that Side Matter seems to work here:

But not here:

Any help?
