How to get Melody singback to treat octaves differently?

[kfJvJ]

I'm trying the melody singback exercise, and it doesn't seem to care which octave I'm singing in. If I deliberately sing an octave too low, I can still get the right answer.

Can I change the settings to avoid this?

Hello,

There used to be an option that required users to sing at the exact octave of the questions (Answer identification-->Fixed), but it has been removed in version 7 because it caused a lot of support requests.
