Formatting Inconsistencies – Woocommerce

Hi, great job on Chicago Theme. It is easy to use and looks great! I upgraded to Chicago Pro mainly because I wanted to use it for my Woocommerce shop. However, I'm finding the theme is not fully integrated. Particularly, the colors, buttons, text etc. As an example, when I am on a normal page, I have a large, bold header with a line underneath. When I am on a Woocommerce page, the header is small with no line underneath. Also buttons in Woocommerce pages are different color / font etc. How can I get the theme formatting to be consistent throughout?
