Premiere Pro relinking audio incorrectly
I am working on an important project for Broadcast and we are having a repeat issue with audio clips relinking to the wrong parts of the reference files.

Note the audio clips with 'duplicate clip' marks and stripped lines through them on Audio tracks 1 and 2.
The camera audio relinked perfectly but the external audio is having issues and relinking to the wrong parts of the same clip.
All clips on Track 1 are referencing from one long .wav audio clip (4hrs) that was used as a sync guide on the shoot.
Any help greatly appreciated.
