Can't insert 2 sets of clips from 2 cameras by timecode

Hi. I have about 20 clips from each of 2 cameras. Both have timecode based on the camera internal clocks. Clocks were perfectly synched during the shoot. I've tried multicam in the cut page, edit page and now "Insert clips into timeline using timecode."
Clips all have cameras numbered 1 or 2 as per manual. Using Cut and Edit approaches, the clips never align correctly even though the timecode is correct per frame.
In the Edit page "Insert clips..." approach, I cannot see how to drop camera 1 clips into Video 1 track (which works) AND then camera 2 clips into Video 2 track. Camera 2 clips just overwrite Camera 1 clips in Video 1 track. Disabling track 1 did not work.
