changes made in Css Designer don't show up in css code

I'm working with a Dreamweaver starter template (in Windows.) When I make a change to the css code, it does not change in the css designer panel. Also vice versa : when I make change in the designer panel it does not change the code. This problem is only apparent in the website I'm building from one of the adobe starter templates.
Another page I built by following a youtube tutorial video does not have this problem. You see how the code states aqua. The css designer panel and the page preview both show the dark red color.
I really don't want aqua or dark red. It is a png image and I want its transparency to work so I don't get anything there except the dark-blue background image on the page. .But I may need to solve this problem first.
