Why my total balance at the MinexBank (available for parking + parked) is by about 0.0034 MNX smaller than the balance shown in my MinexWallet ?
Your coins at the wallet is at 2 or more addresses. you need to use coin control to send them to Minexbakn address. Settings---options--wallet---enable coin control than press inputs in sending menu. Tick box form another address and send coins to main address( do not forget about transaction fee)
All my coins at the wallet are at one address.
Coin control features are enabled in the wallet settings.
In the Send -> Inputs all addresses in "Received with address" are the same.
