[Plugin: Jetpack by WordPress.com] sharedaddy not working on posts

i recently installed jetpack and figured i’d give sharedaddy a try. unfortunately, it does not seem to load on my posts.

if i select Show sharing buttons on posts and pages, i get nothing at all. however, if i select to show the buttons on posts, pages, and index, i atleast get sharing icons on my homepage (https://www.toonbarn.com) however, no other page.

any ideas?
