I did not realise you re talking about SmartConsole. This seems to be a cosmetic bug of sorts.
Check your licensing on VSX nodes themselves, with vsx stat command.
It should show the active licenses and amount of slots available for you:
Name: MyGateway
Security Policy: MyGateway_VSX
Installed at: 10Dec2007 10:31:25
SIC Status: Trust
Number of Virtual Systems allowed by license:100
Virtual Systems
[active/configured]: 2/2
Virtual Routers
and Switches [active/configured]:1/1
Total connections [current/limit} 4/46000
For the SmartConsole, you can try fetching the licenses, but I am pretty sure that error can be ignored. If it bothers you, please open a TAC case.
