Unknown Token in Ethereum Wallet

Hi, last time I have checked my Trezor I have found an unknown transaction into my Ethereum wallet. There ist an amount of around 750 RIFTDAO tokens in my Ethereum wallet. There is no balance/value next to the amount of tokens. Also I have only generated 4 tokens in my ETH wallet, but on the Ethereum account it shows that there are 5 tokens in my wallet.
How ist that possible and how can I get this solved, meaning how do I get rid of this transaction and token in my wallet? I did not touch the token. I can see the transaction (day, time and amount) on the Ethereum transaction history in Trezor, just like a regular transaction.
Appreciate any helpful advise. Thank you.
