WP Rocket caches currency

Hello, I bought your plugin WooCommerce Multi Currency. I installed it and everything looks very good. But my second plugin that I use to cache my site WP Rocket . It also caches your plugin, and it becomes impossible to select a currency. When I disable the caching plugin, or update the cache everything looks good. But as soon as the page cache is created, your plugin just stops responding. If I go to my site with a username and password, it looks good. But as soon as I log out of my account your plugin stops changing the currency.Please help me solve this problem. Thanks you
