Device Details Page and Superseded System Update Information

In ZCC Device Details Summary page, System Updates Status and Source information is listed for "Update Assigned", "Update Completed" etc.  However, after the system update is superseded by a later update, the Device Details Summary page does not list "Update Assigned", but does show "Update Completed"

This is working as designed.  The assumption is that the newer system update will be assigned, and that the details for prior superseded system update is not needed except for the case of "Update Completed".   However, the ZCC / Configuration / System update page will still show pending devices for the superseded update.
