EB5 ACL Having issues need assistance with Permissions Help ASAP

I am having issues creating categories with the correct permissions for viewing and editing/submissions.

I am assigning users to usergroups for example

User1 assigned to Usergroup1
User2 assigned to Usergroup2

I am then creating categories and editing the category permissions to General > Pivacy > Assigned Joomla User Group

Assigned permissions > View the blog posts > I leave all Selected
Select category during blog creation / edit > I select only the Usergroup that can edit the category

This works well for creation those members of a group can only see the categories they have access to.

But a problem exists when a user that only can add to a certain category now views a blog post for different user they are able to edit this post which they should not be able to do. What am I missing.

FoOr example category Mr. Z's Bobcat Update has

Assigned permissions > View the blog posts > All Selected
Select category during blog creation / edit > SuperUsers are selected only

But any logged in User can view this blog post and edit from the frontend
