I have two bitcoin core full nodes. I have one wallet.dat file on both nodes. One node is a master and second node is a reserve. Master signs and sends transactions. Reserve node only receives updates from network. I create new addresses on the master node only and the reserve node derives the same addresses.

I don’t use any other commands on the reserve node. The reserve node creates addresses automatically after receiving a transaction to a new address. This process is possible due to using BIP32 key derivation from one master key.

So, I have constantly synchronized master and reserve nodes. If there are problems with the master, then I switch to the reserve.

I see some strange behavior appear during this process. Some transactions are not shown in the `listtransactions` output. I did a research an found that only "in-wallet" transactions are not shown in the `listransactions`. The "in-wallet" transactions are transactions that were sent with sender’s and receiver’s keys, which are stored in my wallet. I also found that new addresses on the reserve node are created whithout a label.

After adding a label to the address the problem is gone. But adding a label requires additional steps I want to avoid.

**Expected Behavior**

Results of `listtransactions` also shown "in-wallet" transactions to addresses without labels


**Current Behavior**

Results of `listtransactions` doesn’t shown "in-wallet" transactions to addresses without labels

**Possible Solution**

- Automatic adding of a default label to the addresses, derived to the reserve node.

- Print transactions sent to addresses without labels in `listtransactions`.

**Steps to Reproduce**

1.  Run and sync full nodes A and B.

2.  Stop nodes A and B.

3.  Copy wallet.dat from node A to node B.

4.  Run nodes A and B

5.  Use `getnewaddress` method on node A 10 times. Let’s assume the 10-th address is `$ADDRESS`.

6.  Use `sendtoaddress` method on node A. Send 0.001 coins from another address to the `$ADDRESS`. `bitcoin-cli sendtoaddress $ADDRESS 0.001`. Let’s assume the result txid is `$TXID`.

7.  Use `listtransaction "*"` method on node B. You don’t see the `$TXID` transaction in list.

8.  Use `gettransactions`, or `listunspent` methods on node B. You can see the transaction details. Wallet balance changed on node B and is equal to node A.

9.  Use `getaddressinfo $ADDRESS` method on node A. You can see that address had the default label (`""`).

10. Use `getaddressinfo $ADDRESS` method on node B. You can see that the address doesn’t have any label.

**Context (Environment)**

The problem is occured on any version of bitcoin core testnet and mainnet. The problem is also occured on litecoin and any bitcoin-based coins.
