   `prioritize_critical_css` works removing the css file link from the html code, change it by a css snipet (those used above the fold) and then put a javascript snipet at the bottom of the page wirt an onload event to load the rewrited css files.
   You are viewing 2 css files both w/o any rewrite by pagespeed?
   I ask for that because maybe you have a preload hint in the http headers, not in the code. In this case, the browser load these files 2 times, 1 not rewrited by pagespeed (cause pagespeed don´t rewrite link headers) and 1 more time because the css (rewrited by pagespeed) is loaded in the code.
   These 2 files are different because in the header link is the original (https://yoursite.com/some-path/file.css) and in the html code  the file is loaded with a different url ( https://yoursite.com/some-path/file.css.ce.pagespeed.HASHCHAIN.css).
   
   Can you share a url to test?
