Disappearing Audio Channels (Multichannel Timeline, Adaptive Clips)

Mac OS 12.6.2 PPro 23.1.0

This is a follow up / clarification of previous post.

I have adaptive audio clips (4 mono, 1 clip) in a Multichannel timeline (6 channels). The clips are randomly having channels disappear - some clips still show up with all channels, others only 2 channels. I've no reliable predictor on which clips have channels disappear.
