Slider Controls not center aligned

Problem/Motivation

While going through the theme for issues I found out that the slider controls are not centre aligned but right aligned. Attaching the screenshot for a better understanding and making the issue clearer. I have installed and tested the theme over the sandbox and found the issue.

Steps to reproduce

Install the theme
Add 10-20 articles and add slider content and check for the slider controls position.
