Posts aren't populating blog_template page using Chalk Theme

My site is a small tech blog using the Chalk theme. tech.minnix.dev. I've created an empty "project" page using the blog_listing template. My individual posts are using the post template and linked to the project page, but I don't get the post listing on the project page. Within the admin it looks like this.

In the Chalk demo it looks like this http://chalk.paulmassendari.com/blog for the post listings where as mine is empty. You can still view individual pages on my blog via URL like this /projects/tasmota-fcmila but there's nothing on the project page itself. Do I need to populate the blog_listing template page or something?

Thank you for the help. That's exactly what I ended up doing. Lazy Badger on Discord helped me out last night and suggested the same thing. Thank you both.
