"No option available for selected operating system" / provision discovered host, when media is not created with local admin account

Problem:
Using a RedhatSSO account with all roles selected when adding a new installation media : no error
But it’s not visible when I login using the admin account.
Moreover when a new server is discovered and I try to install/provision the OS is well available but in the Media (*) field : nothing is available and the “No option available for selected operating system” is displayed.
When I run all the tasks using the local admin account, everything is OK.

Expected outcome:
Media field shoud be available and selectable
