Cart and checkout pages is not working.

Where is 10 star to give this plugin, I really recommend these plugin to anyone who wanted to remove or change woocommerce build-in features the plugin has ability to remove or change almost all woocommerce features, the one I love the most is the well-designed woocommerce thank you page.

but unfortunately the plugin is not working for me “cart page” and “checkout page” is not working I wanted to change the “place order” text and the botton color and remove some woocommerce fileds but after I published the settings nothing seems to change, same thing with cart page I changed the “proceed to checkout” text and the botton color and then published the settings but nothing seems to change. I deactivated all plugins and remain storecustomizer and woocommerce only and tried the settings again but nothing seems to work, please any idea to resolve this issues?
