Actually this is very strange.
I tried that command in both machines .
Listreceivedbyaddress 0 true then it shows
Both machines came up with the same address starting with 1 the legacy address with funding of the same amount.
However machine 2 came up with the address starting with 3 at the start with more coins inside?
But this seems so weird because on both machines the gui front page on the wallet shows received coins to the address starting with 3
Address.
Try opening Bitcoin Core again, loading both of the wallets, and then issue the RPC command
rescanblockchain[/teal]. Then the transaction history will be in both wallets and you should get the correct listreceivedbyaddress outputs for both wallets.
