[Plugin: Jetpack – Sharing] Buttons display vertically & More button not working

I’m using the theme Novelti (http://www.themeskingdom.com/wordpress-themes/novelti-responsive-magazine-wordpress-theme) and the Jetpack plugin.

I’m having an issue with the Sharing module. It is displaying vertically instead of horizontally (see here: http://alwaysinmotion-sae.org/2015/05/13/a-roadmap-for-mobility-connectivity/). I’ve removed “float:left” from all CSS in the Sharing module files but that has not fixed the problem. Any ideas what else I can do to fix?

Also, hovering over the “More” button does not cause the additional sharing options to appear. If clicked on, it goes here http://www.themeskingdom.com/wordpress-themes/novelti-responsive-magazine-wordpress-theme/#. Is this being caused by the icons appearing vertically or is this a different problem altogether?
