trying to get buttons to appear below previews

This plugin was working just fine before I removed the Facebook icon. I use about 8 icons and they used to appear at the bottom of every preview (below the “read more button), but now they are only appearing after the entire completed post only.

This is despite having selected them correctly on #3 in the settings: “Where shall they be displayed?”

Display them: On Post Pages
After posts: On Homepage

For both settings.

What happened, or what did I do wrong?
