Which entry did you add to the group? I think the short name has the mac address on it while the fqdn doesn't. You can see which on it is as it is listed in the account information in wgm.

The reason getting the one with the mac address on is because that's what it uses to see if it has to apply any preferences, which is why using multiple vlans means you have to bind as the mac address is not know to the server for other vlans.
