on a stock F-91W, that digit will only display 0-6, so the designers tied the top and bottom segments together (since all of those have both segments on). Just means we have to get creative to display characters that use just one or the other, like U or 7. https://joeycastillo.github.io/Sensor-Watch-Documentation/wig/display.html#limitations-of-the-clock-digits
