I had the same problem.

Try adding "neighbor RR-PEER-V6 activate".  Alternatively, I think if you add "send-community [both]" to each individual peer, it fixes it too.  My recollection is a little fuzzy, but one of these two should work.  Let me know if not.

It struck me as strange that the peer was already "up", so it would have never occurred to me that the peer-group itself needed an activate.
