Cache files are deleted when the woocommerce session is open

Hi

I have a problem with a website that uses Woocommerce and WP Fastest Cache. I allow logged in users to use cache by disallowing cache for specific pages and it’s ok, logged in user can browse through cached pages. The problem is that if I put a product in the cart by starting a woocommerce session, the files in the cache are deleted (I checked by connecting to the site via FTP).

Is it working properly? What can I do to fix the problem?

Thanks in advance
