Problem with the theme

I have some problem with the a shopping theam Proteo. I have installed one and I have now some pages dubbel, for example “my Account”, Privacy Policy and shoping. The problem I have is with the shopingsite. The one that seams to work with the products in do not have the side bar management and I don′t know if I can use YITH WooCommerce Ajax Product Filter. will it work anyway?

Can I take som pages away and wich in that case?

I allsow have som issus with the sidbar configuration. when I go to the widgets and Sidebar2 I cant edit it somehow. Do you have a tutorial for this?
