Editor is working, Publishing is not working

Hi, I bought the template for the website.

I want to change the first main video width to 100%, so I changed that.
It seems like working in the editor, but it’s not working when I tried to publish it.

I checked the css, and I couldn’t find the class name inside of webflow.
It’s not changed from 45.2%
