Can’t determine the value of a Uniswap Transaction

I added a MetaMask wallet which contains $ETH and $FWB (a token on the dex Uniswap )

CoinTracker correctly shows the amounts of $ETH and $FWB but it doesn’t show the $FWB in my cost basis.

If I look at the transaction where I traded $ETH for $FWB, the cost basis is there but it says “ Could not determine the value of this transaction.” Does CoinTracker not support Uniswap?
