2nd audio source drops off after fixing sync

I have footage where there was a production sound guy who provided a 6-channel polywav file. The internal recording for the lav was also provided as a 2nd audio source. The camera timecode is off by 1 frame; so, after AutoSyncing in DaVinci by timecode, I have to fix sync. It is very difficult to fix the sync by 1 frame; I would fix it, then do a test render, and the audio will have moved 2 frames instead of one. By going to Media Pool / Select clip / Audio / Waveform / click "unlink" icon, then moving the audio 1 frame (which moves it two frames), then moving it back 1 frame, the test render came out correct. However, the 2nd audio source (lav internal recording) would disconnect from the synced clip.

How do I fix sync by 1 frame while keeping both production sound sources connected to the synced clip?

What if you synced by sound instead of timecode?

Thank you for the reply. I tried that as well, but got the same result.

They were a frame out of sync when syncing by audio?

Not sure would cause that. All frame rates are identical? (Even 23.976 and 24 are technically 'different'.)

Production didn't record scratch audio, so I wasn't able to sync by waveform. That might have saved the day.

Ahh.
