If the group info goes away only after going to book details or the content server, then I can reproduce the problem. Is that the case for you?
EDIT: I just got the debug log from Steven, and it confirms what I think is happening. FWIW: I will get the logs faster if you change the address to send them directly to me. Use the address cc_debug_log at charles dot haleys dot org. Or not ... Steven will forward them to me as soon as he sees them.
