Audio is out of sync when importing AAF

[zeganaudio]

Hello

I'm prepping a film that I'm sound editing and mixing and we're running into an issue. I've imported the AAF via import session data and the audio tracks are out of sync. I confirmed that the editor synced everything prior to sharing AAF with me. I attached a screenshot - you can see that the waveforms of the different microphones are not aligned and slip backwards out of sync as you go down each microphone track.

I should mention that upon importing AAF i received this note "Some clips had invalid bounds and were adjusted or deleted. Some renderings were missing." See attachedment for screenshot.

The editor used Davinci to edit.

I'm using Pro tools version 2019.6.0
Mac OS Sierra 10.12.6

thank you so much for ur help
