I'm curious how was this published October 26, 2021? (Currently Oct 15)

That's the real advance! :)

PNAS recently moved to a continuous publication process so the paper comes out in the planned issue whenever ready rather than effectively coming out twice: once ahead-of-print and once in the issue.

Probably the date of the print publication.
