When you import are you dragging and dropping or are you using the File/Import menu? I've never heard of some tracks being in Elastic and some not upon import.

Go to...
SETUP/PREFERENCES/PROCESSING/ELASTIC AUDIO -
Make sure that Enable Elastic Audio On New Tracks is NOT checked.

And what do you mean it doesn't line up correctly? On the Audio Import Option you can make the audio go to the session start, the selection (where your cursor is), or Spot.

If this isn't working also, you can try to import and put the file in the Clip List on the right. THen you can drag where ever you like.

If your audio files are moving around then i'm wondering if those tracks are in SAMPLE or TICKS.
