Child Theme Style.css Persistence Issues

Hey everyone I am having some very odd issues with my wordpress site. I am using a child theme and am trying to make changes to the Style.css file in the theme editor. My site is hosted with wordpress engine and the issue is I put a code comment at the top of the Style.css file to see if my changes are reflecting in browser dev tools and sometimes I can see the comment and my changes reflected but most of the time I cant. It bounces back and forth and I am trying to understand why. I dont think I have a local caching plugin and I am also clearing cache on wordpress engine my host. Any ideas?

EDIT: I have even SFTP into the files and made sure my changes were present.
