Some of unknown icons on home tap of system manage homepage

[CA1309026]

There are some of unknown icons on home tap of system management homepage.
I installed PSP successfully so there is no problem on agents.
Unknown icons are "Virtual interface 1", "Logical Disks", "Power converter", "Standard IDE controller (1)", "Exp Board", "Version control"
I didn't set up version control agent so it is natural status of version control agent is unknown.
But beside of it, I didn' t understand the reason of unknown status.
How can I fix it? Or is there any reason?
I attatched snap shot of SM homepage.
