Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
From your screenshot, it seems that the post type doesn’t include support for the editor, and when that happens, our plugin can’t update the preview correctly.
However, to ensure that the meta title and description you have set are already applied, you can verify that using these tools:

Let us know how this goes.
Thank you.
