Distraction Removal People Does Not Find All People

In the attached photo, most of the people were found. But, one very obvious person in the lower left is completely ignored. Any idea what’s going wrong here?

Lightroom Classic 15.0.1

Macbook Pro running Tahoe 26.5.2

P.S. I should note that it’s not that critical on this photo since I can just change the aspect ratio and crop all of the people out. However, I would like to know if I’m doing something wrong so that I can get it right for other photos.

P.P.S. Here’s the original photo exported in lower quality in case it helps to research the issue.
