Hi.
As far as I can see the payout multisig went as it should. Any other problems I am not competent to deal with. I suggest to contact a developer to get the remaining fund out. Before check the wallet balance. It may be that the balance is correct and the app is simply displaying a wrong message. In this case one can deleted part of the database which is corrupted. First take a backup of course. See: Switching to a new data directory
