Importing Tracks From Another Project - not translating correctly

Hi, When importing tracks from another project is there an explanation for why some tracks don’t transfer all the data? Some tracks are completely empty when they shouldn’t be (all missing audio files have been located though).

Also, I found that when importing the tracks…they all were in the wrong place and the cue went from a few minutes long …to some of the last musical data being 8 hours from from the first?!? I had the ‘Import to Absolute…’ option checked and I had also previously imported the other projects tempo. Furthermore, all the stems are some how starting before 00:00:00:00??
