Nitro bug?

Hi all!
When I start the game, I hit the esc button and restart the game, I discovered one thing: some kart still using nitro although the race was during penalty time (see picture below). Is it a bug?
One more thing: I translate 'set' (in ready-set-go) into 'Đặt' in vietnamese, but it appears 'Đ T' (see picture below), how can I correct it?
Sory for my English, my English is bad. Hope everybody understand me.
