Styling off on Pro Sites Pricing Table

Hi, I recently changed my theme, and now the CSS styling on the default Pro Sites is off.

Do you have any idea at what could be causing this? I did some debugging myself in Chrome Developer tools and the padding is set at 20px for the ul.feature-section, and changing it to 0px fixes that issue. I do not know where to put that in the code, however. And, I do not know how to fix the other issues.
