2 questions:
1. After I closed a lightning network channel and force closed another one, my coin was split into 3 addresses: 1 was the main mount, the other 2 were for the channels and they became "change" type.
Can I make them back into one address again? Because I usually view my wallet balance through blockchain explorer using one address.

2. After I force closed a channel, the offchain credited the wallet around 1.8mbtc, so that the ledger showed the amount balance of 36.6mbtc. However the summary coin balance only shows 34.6 mbtc.
why there is a discrepancy? This means that the offchain credit doesn't reflect to the coin balance even though the transaction is confirmed on chain. What is going on?
