Pagespeed shows “?” for desktop when cache system is enabled

Hi,

I was trying to add your plugin to my website for caching purposes. I set up my Cloudflare account and clicked the options for caching. When I tried to check my website on PageSpeed, I observed that there is “?” mark for the desktop test. I started to unclick one by one all the options and checked on PageSpeed. Found out that when I enable the cache system, PageSpeed shows “?” mark. Can you please help me on this?
