New coinbase Wallet, received ltc dont Show Up in my wallet

I created a coinbase wallet and sent 5.45 Ltc to the correct adress. Everything worked fine. So i got all confirmations and the wallet said i received the ltc, but they dont show up in my Wallet. My Wallet still says 0.0 ltc. How is that possible? There was only one transaction(received ltc), nothing else. Can someone tell me, whats wrong.
