I have tried disabling the social icon sharing settings in Enfold > Blog Layout > Share links at the bottom of your blog post, and saving, then re-enabling them and re-saving. This is not an issue in Chrome. I think this is new as I seem to remember seeing all icons in the past (note: the email icon [an envelope] IS showing up just fine. The colors also show up when you hover over each empty block).
Ideas?
