Audio Files producing two track Stereo files vs Mono

[MDS2]

I have been using Zoom Meetings to Record Guest interviews for my podcast for two years.  I have always been able to produce the separate files for each speaker and have them produced in MONO format for uploading to Audacity (where I do my editing).  Last week They started to produce as multi track stereo files (two tracks per speaker).  I checked all my settings, even uninstalled and reinstalled Zoom, but still am having the issue.  I am getting separate files for each speaker still, but they are no longer mono.  Not sure where else to look. 

I have original sound for musicians checked and High Fidelity music mode but DO NOT have Stereo Audio checked
