aurora 16 outputs

Hi! First of all i want to say hello to everyone, i'm new here ;)

I have a question about my configuration and maybe you can help me:

In my studio we have the aurora 16 + rme fireface 800 connected to the console: Raindirk Audio concorde 24 channel (1981).

1-8 (+ 9&10: headphones, 11&12: spdif) trough rme fireface 800
9-16:  ADAT I Aurora
17-24: ADAT II Aurora

When I record, it works OK. But once I have recorded and want to mix sending signals on to the desk, only 1-8 outputs go to the desk. When I send the rest of channels the dont go out through the console, but I can watch the signals in the total mix mixer.

Is this normal? Anyone can help?
Thanks!
