One of the styles in main.css (the main theme styles) were being applied to the icons in in Sharebar.
Specifically it was .post ul li{} which impacts “post” list items within “unordered” lists. As Sharebar uses unordered lists to display the icons, the arrows were added.
You can implicitly set a reset/block of some sort given that most blogs will no-doubt have their own styles for listed items, but we were able to add in a specific rule that counter acts the arrows by including the Sharebar element id (we made a specific rule to ignore the main.css rule and display normally).
