I am using Metamask on Chrome. While I was clicking to send ETH on Private Network (localhost: 8545), I have been getting an error about "Unknown props network, identities, addressBook on tag. Remove these props from the element." in Chrome Console screen. It is ok for connection and ETH balance.

Do you have any idea for this problem?

It sounds like you're looking at the MetaMask UI console. This is a react warning about some properties that are being passed to a component. It shouldn't affect your usage of MetaMask at all.
