As of recently, only 3 of my Share icons are appearing. In Settings, I indicated to show Facebook, Twitter, e-mail, print. I also indicated add’l Share options of Digg, Stumbleupon, and Reddit to appear behind the + Share button. Only Facebook, Twitter, and print are showing. When I first set up the share icons about a month ago, they all showed as they were supposed to. Not sure when this started, but I noticed yesterday that only 3 were showing. Help!
