Need help with social sharing and linking plugin

I'm using a plugin to add social sharing at the bottom of blog posts and my social links in a widget in the blog sidebar.

In the CSS there is a border-bottom property applied to "a" and "a:hover" elements on my site but I don't want the social icon links affected by it. I've managed to figure out how to remove the border-bottom from the social icons on the home page and on the main blog page, but on blog posts the border-bottom still shows up on social icons (both in the sidebar and at the end of the post). I want to know how to remove the border-bottom from my social icon links on blog posts as well.

Also, a duplicate of the social sharing links is showing up in the footer of the page on blog posts instead of just at the end of the post, I want the duplicate social sharing links removed from the footer on blog posts.
