Need Help With Davinci Audio channels!

Hey! Sorry if this is dumb question, but I imported footage into Davinci Resolve 18 that had the actor's mics recored directly to camera. One actor was in the 1st channel, and the other actor was in the 2nd channel. But when I put the clip into a timeline (or even examine it in the Media section), only the 1st actor's mic appears with waveforms. The 2nd track is there, but completely silent. It doesn't even register. I've messed around with the various channel configurations in clip attributes and messed around with the audio in Fairlight, but nothing seems to work. I even imported the mentioned clip in FCP and it was perfect. Both actors' audio was there and the two channels. So, whaat am I missing? Any help is greatly appreciated!

Michael, can you provide a sample of your footage to examine?
If you do not want to make it a public link, you can upload it to my server and I'll have a look:

Robert, yes! Thank you so much for taking a look! I'm am uploading it to your server now!

I think I may have gotten close to figuring it out. When am using proxy media. When I unlinked the proxy, that second audio channel appeared! I'm not sure I understand why. Maybe a setting for proxies needs to be changed. Any idea what? I really appreciate you getting back to me on this.

I have tested your clip in a timeline - it contains a stereo track (L/R) and put into a timeline with an audio track set to stereo it will register both channels in the mixer panel. Resolve does only show a sum of both channels in the timeline preview, but by right-clicking it and selecting "Display Individual Audio Channels" it does show both.

So it might be an issue with your proxy files only.
I found a long thread about this issue:

Thank you so much! You have been a huge help! I think I've figured it out. I really appreciate your help.
