Interface Working Differently

Hi there,

I'd love to ask you for help since I'm having problems with CSS Designer in Dreamweaver. As you can see in the video, both media-queries and most selectors have disappeared and I can't click on the items, and thus can't edit them in the right collumn.

I thought I had made some mistake in Preferences or Settings, but the issue still does persist even though I've completely reinstalled Dreamweaver.

Thank you so much for your time and help,
Daniel
