You can have a choice between fixed light and side light framing styles to suit your project. Essentially it shows how a different look can be achieved with a different choice of window or door frame, and may help you decide which option to go for.
The image on the left is with fixed lights, giving a slightly bigger glass look and a clearly defined door. The second image is with side lights, the door opening is still only the middle two panes but the side lights match the doors to give an overall balanced pane look. Neither is wrong or right just a different look a different preference.
