Hi,
Is this user an author of this post? If he is not, ‘edit_others_posts’ capability is required.
This module does not give new permissions to the user. It just restricts the existing permissions.
Meta box at the bottom of the post is related to ‘view’ permission for this post at front-end. If you plan to show this post not to the pepperRole only, you don’t need to setup this view restriction.
