‘SP News and Widget’ plugin registers ‘News’ custom post type with the same user capabilities set as WP does for built-in posts. Look at this screenshot.
So if user can edit/create posts he should have a full access for work with news too.
User Role Editor does not show capabilities for custom post type if it uses capabilities from WordPress built-in post type. That’s why you see 0 there. Capabilities are available under ‘Posts’ group in this case.
