Ethereum staking coinbase rewards

Hi, I started staking my eth on coinbase a few days ago. I was watching my lifetime rewards over the first couple days to see how much it was earning. Yesterday I deposited some more ETH into my ETH2 for more staking. My rewards went to zero and started counting again.

Everytime I check it now it resets back to zero again. I'm not sure whats going on. I tried support but couldn't find an answer.
