I think you can chalk this up to BA.com demonstrating it's so called technology to the fullest! FWIW Row 9 are where there are 2 seats forward of the emergency exit. They aren't IN an emergency row as such and offer no additional leg room. Really annoys me they market this row as an exit seat when it blatantly isn't. When in Club config these comprise 9C/D with the adjacent seat blocked as a table in a typical Club Europe style - of effectively solo seats. What's more confusing in your screenshot is the lack of 10C and 10F - row 10 being the row at the emergency exit with the additional legroom - there are 3 seats either side of the aisle in this row (B/E seats blocked when in CE config). Where are they???
