Remove extra share button

I enjoy this plugin but would like to remove the Twitter Share button it automatically adds by default. My site already includes share buttons a the top and bottom of pages and posts, and the default button that comes with the app does not match the style of the other buttons, and is redundant. How do I remove this extra button, which I am currently trying hide at the bottom of posts (only display options in the menu are “top” “bottom” or “top & bottom”). Here is a link to my blog’s About page, which demonstrates the issue.
