Mix and render when one track was time-shifted

Hi! Using version 2.33 on Win 7. I imported three tracks into an existing project that has a single stereo track in it, but I had to time shift that o track in the project to get them all to start at the same time. It seems I can’t mix and render the time shifted track, even if I record a sound file with no audio input.

I need to export all tracks individually so that I can have an engineer import them into pro-tools. And I want all the tracks to start at the same time (obviously). What can I do with the time-shifted track to align it with the other tracks?
