Audio bypassing summing track

Hi,

my latest summed tracks doesn´t seem to route the audio through my main summing track (no signal showed), and therefore doesn´t react to adjusting volume or muting this main track. Output on the summed tracks are (automatic) the same bus number as input on the main summing track. I have tried dragging the tracks out of the summed track and creating a new one, but the same thing happens. It seems that the audio signals just goes to Stereo Out, even if the Output is set as a Bus.

I´ve even tried creating a new Aux channel with the same Bus as input, but the audio still doesn´t seem to to be routed through the Bus for these tracks.

I have other summing tracks where this works as expected, and the tracks (both main summing track, and the summed tracks) settings seemes to be just the same...

Is this a bug, or what could be the cause?
