Preview button wrecks things with custom role, capabilities, post type (1 post)

    I'm using Members to manage capabilities of a custom role that should only be able to edit/publish a custom post type that I created in my functions.php file. After much work yesterday, I got this working, except for previewing edits.

    Using the custom role everything works fine, as long as I do not click the preview button. However if I click the preview button the preview does not show any of the changes I've made since the last save. Then when I press the publish/update button, my changes are not saved/published, but are loaded into the "preview" tab, as if I had pressed "preview". Nothing else happens in the browser tab where I'm using WordPress to edit the post, the spinny spinner next to the update/publish button just keeps spinning.

    Everything works fine from my admin account, and if I give the custom role the "edit_posts" capability that solves it. So it looks like something is wrong with the custom capabilities for this role, but I can't see anything wrong.

    Below is my code from functions.php.

    Suggestions welcome,
