[j-nsp] VPLS multihoming in 9.1

Does anyone know why my multihomed site would not establish PW.
I have a meshed topology of 3 nodes (PEs), and two of the three nodes are
multihoming a single CE site.
In addition, I also have singlehomed sites in my VPLS and they are just fine
(connection is up).
But for the multihomed site I get the LM status on one multihomed PE and LN
and SC status on the other multihomed PE.
Why would I get SC (collision) when the documentation clearly says that
multihomed sites must have the same site ID?
Not sure at all why I'm getting the LN and LM status.
I do have the same RD and RT in all three PEs, but this should be fine.
Can anyone help? Thanks,
Marlon
Here is the relevant config from the two nodes and 'show vpls connections'
