In March, I made a backup of the wallet and continued using the node. In October, I restored my old backup. After restoring the backup, I found that the listtransactions command stopped displaying some transactions made during the period from March to October.

**Expected behavior**

The listtransactions command displays all transactions in the restored wallet.

**Actual behavior**

The listtransactions command in the restored wallet does not display some transactions since the backup.

**To reproduce**

1. Run bitcoin core in regtest mode
2. Create a new address A and generate 101 blocks with sending a reward to the created address A
3. Create a wallet backup
4. Create new address B
5. Send transaction to address B, write TXID
6. Generate 1 block with sending a reward to address A
7. View getaddressinfo B. Verify labels are not an empty list
8. View listtransactions. Make sure there is a TXID transaction present
9. Stop bitcoin core
10. Restore backup
11. Run bitcoin core
12. View getaddressinfo B and listtransactions. Detect that the address does not have a label set and that listtransactions does not contain a TXID transaction.

**System information**

Bitcoin Core 0.20.1 on Debian GNU / Linux.
