I am trying to get the featured image to work properly within this custom post type plugin. I click the "Set Featured Image" link in the post editor and the regular media modal comes up. When I find an image and show the details, the button for it says "Insert into Post". When I click it, it actually inserts the <img> tag into the post body as if I was adding media to a post, and not assigning a featured image. Any idea why it is behaving like this?
I am running version 1.15 of the plugin.
