Hit the icon at the top right that looks like two squares to shrink the window back down, then try manually resizing the window to make the app larger. It's really strange that the app isn't filling the entire application window - I have no idea why that is happening. On my Chromebook, the app expands to fill the entire window when it is maximized regardless of whether fullscreen mode is enabled or not. I've never seen it behave like what is shown in your screenshot. Does your device support rotation? What happens if you rotate to portrait if so?
