Social Integration Buttons Not Showing, Not Linked

Last week the full list of Social Integration Buttons was visible at the Bottom of all my blog posts - in this order: Facebook, Twitter, Pinterest, Stumble Upon, Google+, Linked In

But this week I have noticed the Facebook button is gone / missing / disappeared
And the Stumble Upon button is not linked, and the graphic is not formed properly

Can you please help me resolve this problem?
I use the links daily to help share the posts to Stumble Upon
(* I schedule the Facebook status updates)

Thank You!
