Warnings: A preload was found for

Hello,

I am using this great plugin on my all websites and it is like I don’t have any option else W3TC.

I just noticed that Google Page Speed has started showing warning as per the image;

I don’t know who is preloading these files. I tried disabling many plugins and nothing helped me. Obviously, as these are minified files by W3TC, so disabling W3TC resolves the issue.

Please help me to resolve it. I am thanking you in advance for your kind cooperation as always.
