Why does FCP keeping mixing down audio

Question

I'm working on a school play that we shot with 2 cameras. I edited it with the multiclip feature.
Only problem is when I'm trying to lay down the final sequence, it won't let me lay down 4 tracks of audio.
when creating the muticlip I added the other 2 tracks of audio from the other camera--so there are 4 tracks displayed.
Now when i load them in the Viewer and try to overwrite in a new sequence in only give me 2 tracks of audio-I need all 4 tracks to do the audio mix.
Why won't FCP let me lay down the audio, I've made sure the tracks are connected. I'm an avid editor learning FCP as i go.
I checked the archives but could not find anything useful.
This would seem like a rather easy task.

Answer 1

did a 2 camera shoot for a play. There is audio on both channels of each camera for a total of 4 channels of audio.
I made my multiclips by syncing the audio from both cameras and creating inpoints.
Than i layed those multiclips into a seq. so I can edit it.
When i did this, you can only lay down audio from one camera into the muliclip sequence. So I added the other 2 channels of audio from the multiclip on A3 and A4.
So after the edit, I know have all my cuts in the video timeline and 4 audio tracks in the timeline.
I have 4 sequences like this b/c we had tape changes during the performance.
I now want to take those 4 sequences and create one final sequence(called Master) that has the edited multiclips with all 4 channels of audio but when I load the act 1 sequence in the viewer and try to lay it down in the (master) it only drops down 2 audio tracks...not the 4 that i see in the act 1 sequence.
let me know if i need to take a screen shot to explain better.
