Roles in Assets have a Bug?

[Rita Zweers]

Hello everybody, 

I am confused. 
I onboarded the users via Groups. 

Users with the Permission Role "Users" should not be able to Create/Edit Asset objects. Only Developers, Managers and Admins. 
What are roles? | Jira Service Management Cloud | Atlassian Support

But they can! I just tested it with users that are only in the "Readers" (User) group. Nowhere else. 

Now I am questioning if this is a bug (not the first one we realized..) or did I do anything wrong? Could that role be overwritten by any other Atlassian role?

Thank you in advance :)

Sorted, 
another group was added where it shouldn't be. :)
