I reported that earlier and was told some minor CSS fixes might be included in the next release so the sharing buttons are less messed up.
But actually I was not happy with the internal sharing options of WooC anyways - so I disabled that and installed the "sexy bookmarks"(shareaholic) plugin. works great for normal posts, pages and products as well and looks way better.
Only disadvantage: it wants to be present on custom post types as well and shows up in the featured slider and in callout areas (in case you use that on the homepage), so you have to hide it there via some custom CSS.
BTW - nice site, but dump those auto-translations, any native speaker will runnnnnn away, German version is extremely horrible.... :)
