RHN -- Reboot Systems

Hi, we have a problems with opcion "Reboot Systems" in "System Set Manager" tag "Misc"

If We have selected some systems and go to "System Set Manager" --> "Misc" --> "Reboot Systems" 
and then show thoe following messages: 

--------------------------------------------------------------------------
Confirm System Reboots

Below is a list of the systems that can be rebooted using Red Hat Network.

Select the systems you wish to reboot and click the button below.
No systems.
--------------------------------------------------------------------------

If we selected any options in "Misc". For exemple: "Lock system Profiles" the rhn show the selected system.

What happens?
