Campaign Co-op Scoring problems.

My Wife and I are very competitive when it comes to Halo, so we always turn on scoring so we know who got more points but at the end of EVERY level (we have played through H:CE & H2) the co-op partner (player 2) always receives 0 points. we have tried regular scoring and competitive scoring but both only show that player one had a score. Also during the missions there is only one score displayed rather than a counter on each splitscreen as all other halos with scoring have done.

Am i missing an option? did i forget to check something? or is this just how the co-op scoring will work from now on?
