Audi Mixdown only exporting SOME of my tracks and HALF of the cue itself – HELP!

I have been trying to export my audio mixdown for hours. My sections are selected, they are not reversed. Nothing is muted. Nothing is recording. Everything but the dialogue is Routed to “Mixbus” and “mixbus” is routed to “stereo out” along with the dialogue. Please help me!

(No I don’t know why my MIDI tracks are all set to Left. If you know that, please help)

Your mix bus is set as a mono track. It should be stereo
