It's utxooverride=1 just in one
What? Why? That makes no sense. With this you are telling this client that you want to specifically stake 1 BBP! utxooverride is not a Boolean but an actual absolute value. That means for your "controller wallet" you have to either leave out this line completely OR set it to the amount of BBP you want to stake for PODC (e.g. 20000).
