premiere can only hear multicam track audio placed in tracks 1&2

7 tracks of audio baked into the proxy for each camera so when grouped the multicam sequence has 14 audio tracks, the duplicate 7 from camera b are muted (not disabled). the problem is for the 7 emabled/unmuted tracks on A1-A7 only what is in A1 or A2 plays back. mute A1 and A2 i can see meters playing for the other tracks so there is info but i can't hear it. i have to delete what is in tracks 1 or 2 and move another track into that spot to hear it but then i can. it is maddening. how do i hear all 7 tracks at once?
