Hello,

In the WP Rocket settings, you have enabled the “Remove unused CSS” option. The “Remove unused CSS” option doesn’t work in some cases and does not load the necessary styles: https://take.ms/MYPuA

Unfortunately, we don’t have a list of selectors to fix this since it is always individual for most of the websites.
You can either disable it or contact WP Rocket for help.

Kind Regards
