Depend on username the device selector shows different possibilities.
if i use my username (not admin but full rights ) the device selector give the different switch types under "device type groups" and "switches and hubs" .( 2950, 3550 etc. )
If i use other uername ( full rights also ) only the ip addresses are seen under "switches and hubs".
The first case is convenient for us.
Where is the different in user settings ???
