Not working with my AMPforWP

Hi There,

I have this plugin installed and properly activated for my AMP for WP pages.

I have set up Post and Page Schema and also have it assigned to my custom post types however when I view source on my AMP pages, I am not seeing any injected schema and I have also tested using https://search.google.com/structured-data/testing-tool and my pages do not have the schema that I have set up.

Here are a couple screenshots showing how I have it setup:

So in the second screenshot, you can see that I have Article schema enabled for posts, pages and the “lessons” custom post type however here is an example of a lesson:

https://nationalguitaracademy.com/lessons/chords-in-the-key-of-c-nwm/amp

And when you run this page though the Structured Testing Tool:

https://search.google.com/structured-data/testing-tool#url=https%3A%2F%2Fnationalguitaracademy.com%2Flessons%2Fchords-in-the-key-of-c-nwm%2Famp

It does not have Article schema at all.

I am running the latest AMPforWP version and am using a custom theme based on the AMP for WP Theme Framework.

Thanks in advance.
