Thanks Mikel

My testing to this point has been that the device was connected 
automatically having been pre-registered and paired.

So I deleted the pre-registered entry and re-paired the device. The 
device entry behaved correctly when first paired, however when I left 
the registration in place, unconnected the device and then reconnected 
it, the duplicates reappeared.

In fact each time I selected an entry at random and clicked "test 
speakers" it created a new entry. At one point I had 6 entries all 
working and all the same device.

It certainly looks like a UI issue. I will contact the PA folks.
Thanks for helping me remove the BT side from the query list.
