Automate to Sequence Mono Audio Error

[Arlington Media]

When using the Automate to Sequence (via menu or icon), stereo audio is place on the timeline in mono. And, there is a notation of Ch 1:1 on the clip. The source footage is an HD .MP4 and comes from a Sony PXW-320. The camera has a stereo mic feeding to Ch 1 and Ch 2. I have changed the audio channels under modify clip to stereo with 1 audio clip, but I have also left it as default with 4 mono channels and get the same result.  When I drag the clips directly to the time line the audio is placed correctly as a single stereo track.

I'm on a Mac (10.14.2) using PP 12.1.2. I had updated to the latest version but the issue occurred there as well.

Is that a single mono track, or dual mono?

Single mono track -- with the balance set to -100

What are the base sequence settings for audio channels/type?
