What issues did you have with version 7? Perhaps I can explain the changes.
In version 6, you can’t dock the folders left so the site is full visible to the right. That’s something version 7 fixes.
I can see from the video that you have set some styles on the All Devices tab (the blue dots show that). You were viewing the settings for the Phone tab in the video, which has nothing. So go to the All Devices tab for that selector to remove the style that hides the price.
