70 duplicate CSS files created

Hi –

I have just run a site crawl and found that there are 71 duplicate css files with URLs in this format:

https://thecasinoheat.ca/wp-content/litespeed/cssjs/54b60.css?69df1

Can I purge / delete these duplicate CSS files and is there a way to stop LS plug in from creating them if they are unnecessary?

Thanks,
Mark
