Can you provide a screenshot of what you are seeing in each role? I'm not sure I understand exactly what you are talking about and I'd like to try it myself to see if I can figure it out.
This was discovered to be because of the Self Service mobile UI and Internet Explorer. We fixed it by turning off the New Self Service UI checkbox in Roles and Permissions for user SelfService.
We were told that this issue is resolved in the next On-Premise release.
