Ethermine payouts doe not appear in metamask

Started mining ethereum couple of days ago and I can see the balance on ethermine. When the first payout (0.005 ETH) was sent to my guarda wallet, it never appeared, because guarda does not support polygonscan. I have created a metamask wallet and imported private keys of my ETH address after adding matic network on metamask using tutorial.
After adding the private key to the matic, I see 0.001 MATIC, which is not 0.005 ETH that was mined in the last couple of days. Why is that? What am I doing wrong?
