Kann von Metamask aus avax nicht in die c Chain schicken

Hello, after starting pangolin I created a metamask wallet and sent the first avax to metamask via the c chain. At Metamask it shows me my Avax balance, but as a Ledger 2 address that is connected to pangolin, I did this yesterday. Today I set up the Avalange wallet with the ledger and sent my credit from the old address with the private key to the new address on the ledger. This also worked. I still have avax at metamask and want to send it to my old wallet with a private key via the c chain address. The new wallet with ledger does not show the c chain. unfortunately it just doesn’t work. what am I doing wrong?
