Hello,
Do you have any cache plugin installed? Did you clear the browser cache because the browser cache the CSS files? https://chrome.google.com/webstore/detail/clear-cache/cppjkneekbjaeellbfkmgnhonkkjfpdn/RK%3D2/RS%3DzwqaryCReNAACSfd_oYYPpX0_tw-
Theme Options and WPBakery custom creates inline styles not the css file that’s why you can see them immediately.
Regards
