Devices... Roles... Cannot Remove/Edit a role nor delete a listed server

[ICT Security]

After our new account set up/successful agent installation, I found a Hyper-V (1 system) role created.
I cannot delete it or edit it. When I drill down to the actual server involved (which by the way does not play any Hyper-V role in any sense), I get a spinning icon and then a red error message "Data not available".

How can I remove or edit the role? Or remove that machine from that particular role?
Also is there somewhere in the documentation that outlines the purpose of "Roles" and what I can do with this particular feature?
