Multicam Clip splices into timeline as Stereo only
All my source clips and the multicam sequences created from them are dual mono.

Upon ingest, I modify all clips recorded as stereo into dual mono.

Then sync using the multicam function.
Weirdly, there is one multicam clip that splices over as stereo onto my otherwise mono track timeline where all the other dual mono track clips sit.

Anyone know what the fix is and if you'd like, enlighten me as to why this is happening with this particular clip?
I'm on Premiere 22.6.2. Mac Studio M1 Max
