I think that a better question is how the duplicates got into the
database. ovs-vsctl is designed to prevent this from happening. Is
there any chance you could send us your /etc/openvswitch/conf.db? It is
often possible to find problems simply by looking at the log that is
part of the database.

ovs-vsctl should not allow it to happen, regardless.

There's no way to continue using the configuration file.
