"Any Vision" Keywords Automatically Added?

Bumped into something "odd" this AM and I'm trying to track it down.  I shot a sports event earlier this week.  My typical workflow is to ingest with Photomechanic, edit & upload in Lightroom Classic (14.01), and display on a Smugmug site.

When I looked at an image on the Smugmug site this morning, I saw "Any Vision" keywords on my files that I never added.  Moreover, I can see those same keywords via Photomechanic on images that I ingested with Photomechanic and brought into Classic, but never uploaded.

I can see those keywords on my Smugmug site and via Photomechanic, but I cannot see them in Lightroom Classic.  Smugmug has assured me that they don't automatically apply any keywords.  I'm waiting on Camerabits/Photomechanic, but does anyone know if Lightroom Classic is now adding these keywords?  Thanks.
