Workgroup Manager Bug?

[lehmanp00]

Just started a new 10.8 server (10.8.2 on a Xserve). I'm seeing 2 small but annoying issues with WGM.

If I try to add a computer to a computer group:

1. I don't see 10.7 or 10.8 Macs in the Bonjour list.(Using the ...) (Yes they are on the same subnet and yes I am also using a 10.8.2 client to run WGM). This is either with Wireless or Ethernet. On the server I only see the one other Xserve on the same subnet with WGM.
2. If I try to manually add the computer to Open Directory, I have to name them slightly differently than we did on 10.6 server. (xx1234 doesn't work, xx1234-567 does)

Just small bugs or something else I am missing?
