I think it could be related to the situation described here (it is the same environment, in the meantime updated also from 4.2.8 to 4.3.1) and previous configuration not backed up at that time:and some steps not done correctly by me.After following indications, I tried to import ovn but probably I did it wrong.Is it possible that you added new networks, instead of importing the old ones?If so the old networks would just stay in the database, and we would have duplicated networks like you have now.
