Not sure how you came to this state. In case something goes wrong, the wallet never deletes token and it might have kept token that have been spent afterwards.

This message indicates that the mint you are using has marked the token as spent for some reason.

You can clean up your balance from spent token by pressing on the mint, scroll down to danger zone and press check proofs.

Also, please update to latest version. This is beta software and introduces changes frequently.

Thanks for testing things out and reporting issues 🧡
