Coinbase lets users swap ETH2 for CBETH which is Coinbase's liquid staking solution for ETH2 holders. This enables them to trade CBETH for any other assets (or fiat).
Currently, the swap of ETH2 or CBETH is represented in CoinTracker as a send of ETH2 and a receive of CBETH. It should be showing as a trade.
This problem may cause a negative balance error on subsequent transactions.
