Issue security - User can see all issues when it seems they should not be able to

[Rebecca C]

Scenario in Question

I have 2 groups of users that interact with a project.

• Users-A should be able to see all issues across the project, create issues, etc.
• Users-B should only be able to see the issues where they are a reporter or watcher, they can create issues (see permissions below)

With my current permissions and issue security scheme both Users-A and Users-B can see all the issues in the project.  I am trying to figure out how to limit Users-B visibilty to what I defined above - so they only see issues where they are the reporter or the watcher.
