No report of post type

Perhaps the plugin just hasn’t had time to check those pages yet? This would be more likely if you have recently enabled those pages to be checked.

I tried with Save and force and recheck all pages, same problem.
Some settings in the post type?

Is there anything odd about those posts that would prevent the Google servers from being able to load and evaluate the pages?

You can test one of the URLs here to make sure that google is able to check it: https://developers.google.com/speed/pagespeed/insights/

I used save and recheck and now is OK

Good to hear. Many hosting providers only run the “WP Cron” service on a set interval, such as once every 5 minutes, opposed to the WordPress default of running it on every page load. This can sometimes cause a delay in checking/rechecking results.

I am working on V2.0 of this plugin which will provide some better messaging to make this clearer to users.
