More invisible with mimic css and js wp rocket

Hello,
I have many with your plugin in pro and free verison. The problem that I encounter on all. As soon as I activate mimic css and js from wp rocket. https://whatwpthemeisthat.com/ detects me again … If I do by autoptimize, it works. I would like to use only WP ROCKET and not rocket + autoptimize. As soon as I activate mimic js and css from wp rocket, everything becomes visible again.
Thank you
