Hello,
When u entered the first word it didn’t showed up in the list right? Perhaps it is something related with the old structure …
But u can try to restore in yoroi chrome extension;
Yoroi is also an open-sourced Cardano wallet, but unlike Daedalus, it is lightweight. It doesn’t have to download the entire ledger, instead it relies on a network of trusted third party full nodes for its data and operations. While this is a sacrifice of security, it makes up for convenience. Instead of waiting for hours, with Yoroi you can send and receive almost instantaneously.
To get access to your funds located on your Daedalus wallet, you only need the 12-word recovery phrase and a Yoroi wallet. Yoroi uses a 15-word recovery phrase, so you need to create your wallet first (SHELLEY WALLET), and then recover the funds inside.
!!! write the SEEDS WORD carefully for the new SHELLEY wallet just in case u will need to recover the new wallet !!!
Once you have your wallet created, select “Claim/Transfer” on the side of the wallet.

From here you can select a “Byron-Era” wallet and a Legacy Daedalus Wallet using 12-word recovery phrases. Input the recovery phrase on the next screen.

If you’ve done everything correctly you will see a progress process appear, letting you know that the wallet is being restored.

To finalize the transfer from Daedalus to Yoroi, simply press Transfer Funds and you will accept the transaction to your wallet.

Wait for the confirmation, and you can use your ADA currency as you desire.
Happy delegation!
