Propagation Issue

Question

The scenario:
Oracle database version 11g
I have 3 queues located on 3 databases, Queue A,Queue B, Queue C.
Queue A is configured to Propagate messages to queue B.
Queue B is merely a routing queue with Propagation created to direct incoming messages from A to queue C.
Problem:
I enqueue a message to Queue A which is propagated correctly to Queue B, however the message is not then automatically propagated to Queue C.
If i enqueue the message directly to Queue B then that message is then propagated to Queue C as expected.
There is no entry in the alert log.
Is there an Oracle Bug i am not aware of ? Can anyone help me with this please. i have tried lot's of docs but there is no reference of propagation working for manual enqueues but not propgated messages.
thanks in advance.

Heres some moe details (sorry i'm a Newbie)
*11g Release 11.1.0.6.0 - Production*
All databases have a user a1, with appropriate privilages
--created on all databases*

end;

--Connect to database B*
select count(*) from test_routing_qtable;
*1*
--Connect to database C*
select count(*) from test_inbound_qtable;
*0*
Message does not propagate from A->B->C only A->B
---Enqueue test message in database B
select count(*) from test_routing_qtable;
*1*
--Connect to database C*
select count(*) from test_inbound_qtable;
*1*
It Works from B->C
I can also dequeue the messages from database B as normal. Any ideas please its getting quite urgent.
Thanks in advance
