Can you tell me why only two social buttons are displaying instead of all the ones I have selected?

I have selected a variety of the Social Buttons to display on my blogs but only two are actually displaying. I am not sure if this just happened now when I upgraded to EasyBlog 5.1.5 or if this was happening before.

I have selected the Social Buttons Type of Respective Social Networking Sites.

I have selected Button Size of Large Buttons.

I have selected Most of the Social Networking buttons to display.
