CoAuthors Plus Not Showing Posts Assigned to Author

Details:
I’m working on a real estate website where co-authors are used as the listing agents and their listings are pulled into author.php. In this instance, there is only a single author/agent for this particular post/listing but the listing is not showing up for the assign agent. The post/listing shows the correct single author/agent as assigned using the CoAuthors Plus plugin, but when queried within author.php the listing does not show at all.

This is only happening for this one particular author/agent (have tried deleting and recreating user, changing usernames with different variations, different/longer spelling of the name, etc…).

Examples
The listing page showing the agent/author to the left:

https://www.theagencyre.com/for-sale/34545-scenic-dr-dana-point/

That author/agent page doesn’t show the property even though it’s assigned to that agent/author (it would appear first, before the other listings – the listings showing are just generic listings under every agent/author):

https://www.theagencyre.com/agent/hana-cha/

here’s how it would ideally look:
