Describe the bug
When I use library web3js or ethers js to transfer a token ERC-20. It always shows up this bug. I cannot confirm to send the transaction. But if you send ETH, it still works. I think there is a bug in showing the name of the token (except ETH) in the amount field.

This bug just happens on Metamask version 1.0.9 and 1.0.10 (before still ok) and on the mobile.
