Split Screen Drifting Broken? Has Anyone Got It Working?

In Single player in Free Play mode, select Drift as game type in Race Setup and things work perfectly. As you drift your accumulating score appears centre screen and your total score appears top right. Fantastic!

Do the same in split screen, you start side by side rolling, session starts, but no drift score in centre screen as you drift so you have no idea how well you are doing in your current drift and then the top right total score disappears.

Single player = perfect.

Split screen = both score displays gone.

Any idea how I can get this working?
