Dolby Atmos ADM sync issues

[Dax Productions]

I'm working on a music project, but its Dolby Atmos so I figure I'd have more luck with help in this forum.

Mixing my first Atmos Music record and I'm having a strange issue. In my mix session, I have the Stereo master in the session as a reference. Its phase locked with the tracks perfectly. I've mixed the record, and I'm trying to make a print master session with all the ADMs and the stereo files for reference.

The problem is, the ADM wavs are slightly ahead of the original stereo reference wavs by a different random amount for each song. From about 1500 samples to about 4500 samples.

Is there any way to better sync the the renderer so there isn't this offset when I print? Using the Production Suite locally (no rmu)

Appreciate any thoughts!
