In my setup, I hit this issue.

It looks like the config is pushed to another br-ex bridge, which is
actually not part of the operational topology, but should have been.

In the example below, you can see that bridge 'delta' is the one
that should be br-ex for ovsdb://uuid/17d1993c-7205-417d-bc4f-f314ecb9f0b1
but there is another br-ex (openflow:147594668038470) in config tree.
