Hi!
It’s not possible to show the icons yet, I’m rolling out a bugfix version today, I’ll check how to do that, and if it’s possible I’ll add it as a feature.
For the post descriptions you might have to ask the theme author, it depends on how those descriptions are rendered, I’m not sure. It looks like the description script it’s executing the search shortcode, but then stripping the HTML tags, which gives the weird text, I might be wrong though.
