How to mix the whole project with busses

I have 2 mono audio tracks and stereo output. I make several buss output channels for effects, but when i try to export audio mixdown i get only 1 stereo out channel without busses. How can i export the whole project?

:unamused:
1.What software are you using ?
2.What effects? external? / Internal?
3.What do you mean by “export the whole project”? You export the channels you specify in the export dialogue. MAke sure all signals you want in the export are routed there.
