Metamask is dispalying ETH as AVAX. How to fix?

I have an issue with AVAX and ETH native tokens displaying incorrectly on Metamask extension on Brave browser.

I have the Ethereum mainnet and Avalanche network both on my metamask. After I added the Avalanche network, the AVAX in my acct on the Avalanche network was displaying as ETH in the metamask broswer extension, but if I clicked to view the account in explorer I could still clearly see that this was an AVAX address. I uninstalled and reinstalled the browser extension and re-added the avalanche network. Now the AVAX on the Avalanche network is displaying correctly as AVAX, but I have a new issue on the Ethereum Mainnet where my ETH is now displaying as AVAX. How do I correct this so the native tokens are displaying correctly on their respective networks in Metamask?
