Sorry just saw your later reply. You need to figure out the track assignments of the source - certainly looks mixed up by the waveforms. You can still use 6ch adaptive tracks and route the source tracks correctly for your deliverable (typically either L,R,C,Lfe,Ls,Rs OR L,C,R,Lfe,Ls,Rs). The 2.0 (stereo) clips you could route to just L and R outputs, OR you'll need to upmix them if you want them to be 5.1. There's various plug-ins, but I've never used them in PP. NB You kind of need to work back from the deliverable. My deliverables have always been discrete tracks in an MXF OP1a file - they get played to air pretty soon after we deliver. Indeed we can play to air directly from the NLE.
