Fix issues with wordpress plugins and template

I need assistance with a couple of customization with plugins within wordpress including Wooommerce, W3 Total Cache, and “Woocommerce currency switcher”. 1- I have installed w3 total cache plugin for improvement of site speed and recently I installed woocommerce currency switcher to enable my ecommerce site sell in different currencies. I would like to know if anyone can help me to set up W3 Total Cache in a way that the price component of Woocommerce doesn’t get cached without deactivating the page cache. Right now, because of cache, after the user changes the currency in the shop page using the currency widget, goes to another page and comes back to any page that has woocommerce products in it, the currency is not updated since it shows the cached currency. I already tried to configure browser HTML cache in W3TC by setting the expires header lifetime to zero (0) and cache control header to public cache must revalidation proxy must revalidation according to a guideline but it did not work. Can anyone help fix this? 2- I have storefront theme for my ecommerce website. The theme has a cart menu at the top of pages showing the thumbnail picture of products added to the cart but when user goes to the cart page, the thumbnail of products don’t show up in the cart page anymore. I would like the thumbnails of product pictures to show in the cart page as well.
