Initially, transfer your funds out by opening the Smart Vault and clicking:
In the Transfer window, enter the amount of wSOL you wish to transfer. This will be returned to your original wallet.
Afterwards, select "Transfer funds out" and confirm the prompt on your wallet.
Once the wSOL arrives in your wallet, refresh your page on the Smart Vault.
At the right hand side of the vault you will see the "Available in your wallet" section.
Click the "Unwrap wSOL" button and confirm the prompt on your wallet.
Your wSOL has now unwrapped to SOL and is available in your wallet.
