Hello Joe,


I have one question: what is this controller?

     Bridge "labBR1"

         Controller "tcp:192.168.137.60:6633"

   is_connected: true

Is it an Openflow controller?
My guess is that the traffic on you "switch1" generates packet-in 
messages and those get sent to the controller which in return replies 
with these flows that you think to be default (although they are not).

Try removing the controller then see if the flows get deleted.


Hope this helps,
Andrei
