Woo and Marketpress

Hi, I have started to develop using the above plugins and the payment system I want to use to sell courses via CoursePress Pro needs to be just WooCommerce.

However, when creating a new product there is a secondary payment section added which I don’t need. If I turn off Marketplace I get a popup telling me to activate Marketplace to sell courses. Is there something I need to do so that I can just use of the Woo functionality?
