Hi Aldo,
Edit restrictions add-on support hierarchy for the WordPress built-in pages only. It applies edit restrictions from the parent page to all child pages by default.
I did not meet with usage hierarchical CPT until this moment.
A possible workaround – use categories as working groups. User restricted by category can post to that category only. A problem – parent post will not be assigned automatically.
URE Pro does not restrict parent posts available to a user.
It seems that URE Pro is not ready for hierarchical scheme realized by you.
May be you will think about work with this CPT without hierarchy, separating access to the items inside this CPT just by categories?
